Phosphate ore is a general term for phosphate minerals that can be used as an important chemical material, mainly used in medicine, food, matches, dyes, sugar, ceramics, national defense and other industrial sectors, as well as an important mineral raw material for the extraction of phosphate fertilizer.   China's phosphate ore reserves are currently ranked third after Morocco and the United States, domestic phosphate ore distribution is concentrated in Yunnan, Guizhou, Sichuan, Hubei and Hunan 5 provinces, the total reserves account for about 74.5% of the country, phosphate ore by the formation of two main types of apatite and phosphorite, where apatite is mainly in igneous or metamorphic rocks in the form of crystalline apatite, phosphorite is gray-black, cryptocrystalline microcrystalline structure, breccia structure. Now known to contain phosphorus minerals in more than 120 kinds, now the industrial use of phosphate ore is mainly apatite, in fact, for sulfur phosphorus aluminum strontium stone, blue iron stone, etc., of which more than 95% of the phosphorus element mainly several species in the apatite.  There are more associated minerals in natural phosphate ore, mainly miscellaneous rocks and veins, specifically two types of silica minerals and carbonates. Silica minerals are mainly quartz, quartz square, flint, opal, clay ore or other silicate minerals such as feldspar, mica, etc. Carbonates are mainly limestone and dolomite.      The goal of phosphate ore enrichment is to maximize the separation and removal of impurity minerals and improve the grade and quality of phosphate ore. The enrichment process includes crushing and separation (crushing and crushing), washing and classification (washing and classification), separation and purification (flotation, magnetic separation, photoelectric separation, calcination, heavy media separation), the three main steps. The process and operation of phosphate ore preconcentration and discarding are as follows. 1. Crushing and separation      Phosphate ore enrichment requires crushing and smashing to achieve monomeric dissociation of phosphate minerals and veinlets, mainly because the phosphate minerals and miscellaneous stones are in cementation together, the original ore can only be broken and ground to achieve monomeric dissociation. This step is the basic step of phosphate ore enrichment. 2. Water washing classification     Phosphate ore due to the mining process in the wet ore adhering to the mud, only after water washing to remove the mud, while water washing can also remove soluble water substances and so on. Because the phosphate ore after crushing, water washing particle size is different, you need to go through the classification equipment to sort out the appropriate particle size. Only then can further enrichment and purification. 3. Separation and purification      After the above process, phosphate ore into the final separation and purification steps, phosphate ore purification are mainly heavy media separation, photoelectric separation, calcination, flotation, magnetic separation. 1) Flotation     Flotation mainly has positive and negative flotation, mainly using phosphate ore and miscellaneous ore physical properties are different, the use of flotation agents to make phosphate ore float or sink, so as to achieve the purpose of separation. 2) Magnetic separation      The use of iron-containing magnetic minerals in phosphate ore, under the action of magnetic separator, and non-magnetic vein recovery of phosphate ore containing iron magnetic minerals separation. 3)Calcination     Mainly used to remove organic matter, carbon dioxide and part of the fluorine in the phosphate ore, calcination temperature of 400 ~ 1400 ℃, depending on the purpose. 4)Photoelectric sorting     Mainly phosphate ore after crushing, the use of ore surface characteristics differences, through the color sorter or artificial intelligence sorter for sorting. 5)Heavy media sorting    Using the difference in density between phosphate ore and other minerals, a medium is selected so that one medium floats and the other sinks, thus achieving enrichment.      The above is the way of phosphate ore sorting and purification applications, where the mainstream sorting is mainly using heavy media sorting and photoelectric sorting (X-ray sorting), a small number of flotation, magnetic, calcination process. Next, we will elaborate on the mainstream phosphate ore separation and purification process. First of all, heavy media sorting is the use of phosphate ore, dolomite, shale specific gravity differences to sort, where phosphate ore, dolomite, shale density distribution of 2.2g/cm³, 2.8-2.9g/cm³, 2.55 ~ 2.65g/cm³, in the actual sorting process, subject to the influence of a number of factors, phosphate enrichment has nearly 8% or so dolomite carry out, greatly affecting the phosphate enrichment after the quality.       At the same time, there are some phosphate mining enterprises have used X-ray equipment for sorting, X-ray equipment sorting is similar to heavy media sorting, mainly using the density difference between mineralized and non-mineralized materials for sorting, in the field production process, because the phosphate ore and associated ore density difference value is small, imaging is closer, there will be throwing waste tailings phosphate ore with high, the actual application of phosphate ore is not particularly ideal. The current stage of the situation and problems faced by phosphate ore sorting, the introduction of artificial intelligence sorting machine, the main principle is the use of phosphate ore surface characteristics of the differences in sorting, to accurately identify the phosphate ore and dolomite and shale surface texture, luster, color, shape and other characteristics of the subtle differences, a composite sorting, sorting effect is higher than the current stage of phosphate ore enrichment accuracy and effectiveness.       Mingde photoelectric recently used artificial intelligence ore sorting machine,digital color separating machine, sorting phosphate ore original grade of about 20, after enrichment of the concentrate grade of about 30, tailings in the phosphate ore grade is less than 5. fully able to meet the target sorting requirements. At the same time, it can guarantee the amount of bad material to be taken out under the premise of enriching the phosphate ore grade, and also take into account the rate of good material to be taken out from the waste tailings.   Here is the phosphate ore after sorting Mingde photoelectric focus on the field of ore sorting, after a long period of technical accumulation and ore field of sorting applications, the introduction of four series of more than 20 products, widely used in fluorite, talc, wollastonite, high crystal silicon, iron ore, gold ore, lead and zinc ore, coal and coal gangue, vanadium ore and nearly 100 kinds of metal, non-metallic ore field of sorting applications.     Edit by Jacky

Tailings problem, gold companies to solve this way ......   Tailings usually refers to mine solid waste that is not suitable for further sorting and recovery under the prevailing conditions after mine beneficiation. And tailings storage simply refers to the construction of a dam to intercept the valley mouth or enclose the land constituted to stockpile metal or non-metallic mines for ore beneficiation after the discharge of tailings or other industrial waste places.   At present, there are nearly 10,000 tailing ponds in China, and the number of tailing ponds is large and widely distributed. Tailings pond environmental management base is weak, coupled with the tailings pond pollution hidden strong, some tailings ponds adjacent to important rivers, drinking water sources and other ecologically sensitive targets, pollution prevention measures are not perfect, operation and management is not standardized, environmental risks are more prominent.   Tailings pollution problem should not be underestimated   The problem of tailings is extremely prominent in the mining pollution problems that have occurred in recent years. The 2011 Yunnan Qujing chrome slag pollution incident, resulting in the death of sheep, pigs and undrinkable water; a mining company in Shaanxi Province in 2012 discharged ore processing slag through a river berm, affecting the arable land of downstream villages and the lives and property of residents; 2015, a company located in Longnan City tailings pond leakage, resulting in a sudden environmental incident across Gansu, Shaanxi and Sichuan provinces, causing a certain impact on the production and living water of some people along the line, and directly threatening the safety of water supply to local residents; In 2020, a mining company tailings pond in Heilongjiang Province leaked, causing the local first water plant to stop taking water, and some river sections, farmland and woodland pollution in Yichun City and Suihua City ...... These lessons always remind us that the pollution problem caused by tailings cannot be underestimated and must be taken seriously. The Law of the People's Republic of China on Environmental Prevention and Control of Solid Waste Pollution (amended in 2020) requires that adhering to the principles of reduction, resourcefulness and harmlessness, mining enterprises should adopt scientific mining methods and beneficiation processes to reduce the amount of tailings, coal gangue, waste rock and other mining solid waste generated and stored. At the same time, the state encourages the adoption of advanced technology for tailings, coal gangue, waste rock and other mining solid waste for comprehensive utilization. Tailings, coal gangue, waste rock and other mining solid waste storage facilities after the cessation of use, mining enterprises should be sealed in accordance with national regulations on environmental protection and other provisions to prevent environmental pollution and ecological damage. In 2022, the Ministry of Ecology and Environment issued the "tailings pollution prevention and management measures," "tailings pond pollution hidden danger investigation and management technical guidelines (for trial implementation)" to risk prevention and control as the core implementation of tailings pond classification and classification of environmental management, and firmly guard the bottom line of ecological and environmental security. At the same time continue to promote the Yangtze River economic belt, the Yellow River basin and other key areas, watershed tailing pond pollution management, strengthen the flood tailing pond pollution hidden danger investigation and management, and improve the tailing pond environmental supervision infrastructure capacity, further improve the tailing pond environmental information, build tailing pond environmental management information system, with information technology means to enhance the tailing pond environmental management capacity and level, enhance the ecological environment departments around the tailing pond Pollution management level and environmental supervision capacity. And the World Gold Council also reflects the high importance it places on tailings and emissions management in its 2019 release of the Responsible Gold Mining Principles (RGMP) - we will ensure that environmental responsibility is at the heart of our operations and will follow ongoing management and governance actions that are consistent with accepted practices to design, construct, manage and abandoned tailings storage and heap leach facilities and major hydraulic infrastructure. At the same time, no new mines will be developed that would involve the use of riverine or shallow seabed tailings. Managing tailings gold companies have been taking action   For gold mining companies, the concern for ecological protection and the practice of the concept of "green water and green mountain is the silver mountain" is something that they need to improve and implement throughout their production management process. Many gold mining companies have been exploring and taking concrete actions to address the core issue of tailings management. In order to improve the tailings problem in the mining process, many enterprises use advanced AI ore sorting machine to enrich the tailings, enhance the grade of ore and reduce the tailings throwing. In order to improve the tailings problem in the mining process, many gold mining companies have adopted dust prevention and environmentally friendly mining methods. For example, in order to manage the adverse effects brought by tailings, all subsidiaries of China Gold Group have hardened or greened the exposed ground of industrial sites, and set up wind and dust suppression nets in the tailings storage and coal pile of the boiler house, equipped with watering trucks, and regularly sprinkled the site road surface, ore transportation road and tailings storage, which effectively reduce dust pollution. Ltd. as a tailing-free metal mine is implementing the filling method of mining, most of the tailing sand is used to fill the underground mining area, and the composition of the remaining tailing sand is tested, combined with the characteristics of tailing sand with high calcium content, small particles, easy to form, and high pressure resistance after drying, and actively cooperates with local cement plants and brick kiln factories, and part of it is supplied to relevant enterprises in proportion to maximize the value of the effective use of mineral resources. . The comprehensive utilization of tailings and waste rocks is another practice of gold mining enterprises to explore tailings management. For example, Zijin Mining Group has always given priority to the comprehensive utilization of tailings and waste rocks by means of underground filling, use as construction materials, vegetation restoration, road paving and recovery of valuable components, etc. The rest is stockpiled in drainage sites or tailing ponds that meet the national standards of the location, and the tailing ponds are impermeable in accordance with the requirements of the local standards to ensure the safety of groundwater quality downstream of the tailing ponds. The Group strictly follows the approved design plan for the operation of re-mining, sand discharge and drainage in the reservoir to ensure the safety of the tailing dam and the original flood discharge facilities, and conducts inspection and facility maintenance management in accordance with the relevant requirements of tailing pond safety management. After all the tailings back mining no longer carry out tailing operations, timely to the safety production supervision and management departments to fulfill the tailing pond cancellation procedures. At the same time, the tailing pond will be closed according to the regulations of tailing pond closure after the reuse production is completed. In addition, Anhui Taiping Mining Co., Ltd, a subsidiary of China Gold Group, also provides tailings sand after physical drying to road construction enterprises as raw materials, opening up a new way of mineral resources development and comprehensive utilization, which not only saves resources, but also provides a broader space for the company to expand the comprehensive utilization of tailings sand. Only by improving the utilization rate of water resources and protecting water resources can we achieve the long-term and stable development of gold mining enterprises. The recycling of water resources has also become a major direction for gold mining enterprises in the management of tailings. In China Gold Group, most of the mining enterprises adopt the tailing slag press filter dry discharge technology, adopt press filter dry discharge for tailing, and recycle water resources, all wastewater is not discharged, and the water recycling rate reaches more than 92%. For example, after the tailing wastewater is clarified and treated, it flows into the return dam under the tailing reservoir and is pumped back to the high level pool of the processing plant for flotation production recycling, and the water in the tailing reservoir is not discharged. In addition, Tong Hui Mining, a subsidiary of Zhajin Mining, has invested more than 6 million yuan to build a tailing wastewater recycling system and an underground mine brine water recycling system, and laid a wastewater recycling and reuse pipeline, so that all the recycled wastewater can be used for production reuse after treatment, which can reduce the amount of new water used for ore dressing by more than 2 million cubic meters per year and realize the efficient recycling of ore dressing wastewater. Zero discharge" and 100% "reuse" of saline water under the mine, ensuring the coordinated development and green development of the production system and the ecosystem. For the tailing sand produced by the beneficiation plant, Tong Hui Mining actively carries out project research and development, using the tailing sand to carry out the paste cement filling project, filling more than 70% of the tailing sand into the underground mining area and the former surface collapse area after thickening, reducing the amount of tailing sand discharge, effectively extending the service life of the tailing pond, and generating good social and ecological benefits. In addition to tailings management in the mining process, gold mining enterprises are also exploring and practicing in pre-mining assessment and post-operation ecological restoration. Before the construction of each project, Zhaogold Mining Co., Ltd. conducts environmental impact assessment in strict accordance with the procedures, analyzes the possible impact on the environment after the project is completed and put into operation, and proposes countermeasures and measures to prevent pollution. At the same time, Zhaogold Mining, in addition to conscientiously fulfilling the procedures of environmental protection acceptance of project completion, carries out comprehensive recycling of the waste left behind in the production process, focuses on strengthening the comprehensive management of mining areas and tailing ponds, and does a good job of mine greening, beautification and ecological environment construction to further improve the environmental situation around the enterprise. In February this year, Serbia's Zijin Copper Boer River comprehensive environmental management project officially dug into the construction. After the completion of the project will enhance the tailings storage and open pit safety operation capacity, improve the ecological environment of the natural water system in the downstream section of the Pol River and Timok (Timok), with good ecological and social benefits. Zijin Por copper mine insists on creating a "garden mine" and vigorously implements greening and reclamation. At present, all tailing ponds, open pit slopes and slopes of some abandoned dumps have been greened, with more than 60,000 seedlings planted and a new greening area of about 350,000 square meters, giving the mine and plant areas a new look. The project has also taken many measures to control dust, solid waste, waste water and waste gas, with remarkable results. In addition, some gold mining enterprises have also built a model combining "industry, academia and research" to promote tailings management. For example, Shandong Gold Group, in view of the common problems such as the high emission of gold tailings and the high disposal cost and safety and environmental protection pressure caused by the residual cyanide in the smelting cyanide slag, has organized relevant enterprises and strong scientific research institutes in China to jointly establish the "Joint Innovation Research Base for Resourceful Utilization of Gold Tailings", with the theme of low-cost resourceful disposal of gold tailings. Low-cost resource utilization disposal is the theme, using AI ore sorting machine ,Mineral separator  , bulk ore sorting system and optical sorting machine to enrich the grade ,reducing the tailing, giving full play to the advantages of internal and external resources, to overcome the key technology of resource utilization of tailings, to build a demonstration project of ecological disposal of tailings, and to solve the problem of "neck" of tailings disposal. The waste stone is widely used for underground filling, tailing reservoir dam building, building stone, etc. The tailing sand is comprehensively used for underground filling, outbound transportation, construction materials, etc. The comprehensive disposal rate of tailing sand is greatly improved. Among them, Xinhui Company and Hainan Shanjin Company took the lead in building a tailing-free mine, realizing comprehensive recycling and turning waste into treasure, and its advanced experience and practices are being promoted and applied in other mines. At the same time to strengthen the whole process of standardized management of hazardous waste, the enterprises belong to the establishment of standardized hazardous waste temporary storage room, the strict implementation of the five-linked list system, to achieve the collection, utilization, temporary storage, transportation, utilization and disposal of hazardous waste for the whole process of standardized management.    

Fluorite ore, also called fluorite or soft crystal. Its main component is calcium fluoride (CaF₂) , which emits fascinating fluorescence under ultraviolet or cathode ray irradiation. The crystals of fluorite are usually larger, have a glassy luster, and have bright and varied colors, which makes it unique in the field of decoration and collection. However, due to the low hardness and brittleness of fluorite, we need to avoid violent collisions and exposure to chemicals in daily contact. In the industrial field, fluorite is the main source of fluorine and is widely used in metallurgy, chemical industry, building materials and other fields. In addition, fluorite also has good optical properties and can be used to make optical products such as glasses and lenses. In short, fluorite mine not only has unique aesthetic value, but also plays an important role in industry, scientific research and other fields. This article will take you through the main types of fluorspar and their mineral processing methods. The main types of fluorite ore can be divided according to their gangue minerals. Specifically, fluorite ore can be divided into the following types: Single type fluorite: Single-type fluorite ore is mainly composed of fluorite, with smaller amounts of other gangue minerals, such as barite, potassium feldspar, calcite, pyrite, adolite, kaolinite, etc., as well as trace amounts of phosphate-containing minerals and metal sulfides. Specifically, the grade of calcium fluoride is generally 35%-40%. A few fluorspar with more than 65% can be directly used as smelting-grade fluorspar resources, but the reserves are small and the degree of development is high. Sorting process: Hand selection is mainly used for fluorite ores where the boundaries between fluorite and gangue are very clear, and is carried out through steps such as washing, screening, and manual separation. Photoelectric separation is mainly used to sort granular ores with higher grade ores and particle sizes of 5 to 80 mm. Quartz type fluorspar ore: The main minerals are fluorite and quartz. The content of fluorite can be as high as 80% to 90%, and also contains a small amount of calcite, barite and sulfide. Since its main gangue mineral is quartz, its mineral composition is relatively simple and its purity is high. It can be used in industrial production directly or after simple treatment. Sorting process: The processing process of quartz fluorite is relatively simple and can be directly subjected to physical processing such as crushing, photoelectric sorting, and grinding. Carbonate fluorspar ore: The main minerals are fluorite and calcite, of which the calcite content can reach more than 30% and contains a small amount of quartz. Sometimes the mineral composition of such ores can be further subdivided into the quartz-calcite-fluorite type. Sorting process: Carbonate fluorspar ore has certain limitations in industrial applications. Since both fluorite and calcite in carbonate fluorspar ores have good floatability during the flotation process, conventional flotation processes and chemical systems cannot effectively distinguish between the two, resulting in calcium carbonate ( The CaCO₃) content exceeds the standard and becomes a non-standard product. Therefore, carbonate fluorspar ore is called "difficult to separate ore" by the fluorite mineral processing industry. At present, some carbonate fluorspar ores with good dissociation degree in the particle ore stage are processed by Mingde artificial intelligence sorting equipment. Pre-selecting and discarding waste to reduce the calcium carbonate content, and finally recovering the fluorspar concentrate through flotation. Barite type fluorspar ore: The main minerals are barite and fluorite, with the content of barite ranging from 10% to 40%. This type of ore is often accompanied by sulfides such as pyrite, galena, sphalerite, etc. Sometimes the quartz content also increases, forming a quartz-barite-fluorite type ore. Sorting process: After the barite type fluorspar ore is crushed, for coarse-grained ores, heavy media beneficiation methods are commonly used, such as jig beneficiation or shaking table beneficiation. When the selected fluorspar ore contains heavy metal minerals such as barite and galena, the fluorspar will be recovered as the first heavy material. For fine-grained ores, flotation is often used for separation. During the flotation process, the mixed flotation process and Na2CO3 are used to adjust the pH of the slurry, and the pharmaceutical system uses oleic acid and water glass as collectors and inhibitors respectively to obtain a mixed concentrate of fluorite and barite. The barite and fluorite are then separated by flotation. Sulfide ore type fluorspar ore: Its mineral composition is similar to quartz-fluorite, but it contains more metal sulfides, and sometimes the lead and zinc content can reach industrial grades. Sorting process: Flotation is generally used. First, a xanthate collector is used to float out the sulfide ore, and then a fatty acid collector is added to float the fluorspar. In order to suppress residual sulfide minerals and ensure the quality of fluorspar concentrate, a small amount of sulfide mineral inhibitors, such as cyanide, can be added. The selected fluorspar concentrate is dehydrated and dried to obtain the final fluorspar product. Siliceous rock type fluorite: Siliceous rock type fluorite is formed by sedimentation. This type of fluorite ore is usually distributed in shale, mica quartz and other siliceous rocks in the form of fine-grained disseminated, cement-like, strip-microlayered, lumpy, and oblate lens shapes. Sorting process: After the raw ore is crushed and screened, the coarse-grained ore is generally sorted by heavy media, and the fine-grained ore is sorted by a jig or shaker.  When the selected fluorite ore contains heavy metal minerals such as barite, sulfite, galena, etc., fluorite is recycled as the first heavy object. Sedimentary fluorite: As for carbonate fluorite among sedimentary fluorite, fluorite is distributed in fine granules in limestone and marble, and forms a granular co-bonding mosaic structure or metamorphic structure with calcite or dolomite. The mineral composition of sedimentary fluorspar deposits is relatively complex and may contain a variety of impurities and associated minerals, so more complex mineral processing and purification processes are required before industrial application. Sorting process: Due to the complexity of its mineral composition, sedimentary fluorite may need to adopt more complex processes and technologies during processing, such as flotation, gravity separation, etc. Generally speaking, the sorting process of fluorspar ore may vary depending on the nature of the ore, the performance of the beneficiation equipment and the beneficiation objectives.  Therefore, in practical applications, appropriate sorting processes and methods need to be selected according to specific circumstances,equipment, and at the same time make appropriate adjustments and optimizations to the process flow to achieve the best mineral processing effect.

A. Phosphate Ore Overview Phosphate rock refers to the general term for phosphate minerals that can be used economically. It is an important chemical mineral raw material. It can be used to make phosphate fertilizer, yellow phosphorus, phosphoric acid, phosphide and other phosphates. These products are widely used in agriculture, medicine, food, matches, dyes, sugar, ceramics, national defense and other industrial sectors. Phosphate minerals can be divided into three types according to their mineralization origin: sedimentary rocks, metamorphic rocks and igneous rocks. At present, about 85% of industrially mined phosphate is marine sedimentary phosphate, and the rest is mainly igneous phosphate. It can also be divided into two types: apatite and phosphorite. Apatite refers to the phosphate ore in which phosphorus appears in the form of crystalline apatite in igneous rocks and metamorphic rocks, while phosphorite is an accumulation formed by exogenous action, composed of crypto crystalline or micro-crypto crystalline apatite and other gangue minerals. B. Distribution and development of phosphate resources Globally, phosphate resources are mainly distributed in Africa, North America, South America, Asia and the Middle East, of which more than 80% are concentrated in Morocco and Western Sahara, South Africa, the United States, China, Jordan and Russia. China is a country with rich reserves of phosphate resources, ranking second in the world, second only to Morocco and Western Sahara. C. The main uses of phosphate rock Phosphate rock is an important chemical mineral raw material with a wide range of uses, mainly including the following aspects: 1. Phosphate fertilizer production: About 84% to 90% of the world's phosphate rock is used to produce various phosphate fertilizers, which are essential nutrients for plant growth and play a key role in increasing crop yields. 2. Production of yellow phosphorus and phosphoric acid: Some phosphate rocks are used to produce pure phosphorus (yellow phosphorus) and chemical raw materials. Yellow phosphorus can be used to make pesticides, incendiary bombs, tracer bombs, signal bombs, smoke bombs, ignition agents, etc. Phosphides of phosphorus, boron, indium, and gallium are used in the semiconductor industry. 3. Production of other phosphates: used in the metallurgical industry to refine phosphor bronze, phosphorus-containing pig iron, cast iron, etc. Zirconium phosphate, titanium phosphate, silicon phosphate, etc. can be used as coatings, pigments, adhesives, ion exchangers, adsorbents, etc. Sodium phosphate and disodium hydrogen phosphate are used to purify boiler water, and the latter can also be used to make artificial silk. Sodium hexametaphosphate can be used as a water softener and metal preservative, calcium phosphate salts are used as animal feed additives, and phosphorus derivatives are used in medicine. 4. Other applications: With the widespread use of lithium batteries, the demand for phosphate ore is gradually increasing. Fluorapatite crystal is the most ideal laser emission material, and phosphate glass lasers have been used. 5. Comprehensive utilization: Phosphate ore is often accompanied by uranium, lithium, beryllium, cerium, lanthanum, strontium, gallium, vanadium, titanium, iron ore, etc. Most of them are rare substances urgently needed for the development of cutting-edge industries and can be comprehensively recycled. D. Phosphate mining methods There are two main methods of phosphate mining: open-pit mining and underground mining: Open pit mining Open pit mining is suitable for situations where the ore deposit is shallow, the overburden is thin, and the ore grade is high. This method usually includes the following steps: 1. Surface Clearing: Clearing the surface of the mining area to remove debris and vegetation. 2. Explosive crushing: using blasting technology to break the ore into smaller particles. 3. Excavation and transportation: Use excavators to dig out the crushed ore and transport it to the ore processing plant by transport vehicles. 4. Ore processing: The excavated ore is crushed, screened, washed and processed to obtain ore products that meet the requirements. Underground mining Underground mining is suitable for situations where phosphate deposits are buried deep and the ore distribution is relatively uneven. Compared with open-pit mining, underground mining requires more underground engineering construction, but its mining effect is more stable and the utilization rate of ore resources is higher. The specific steps include: 1. Construction of shafts and tunnels: digging shafts and tunnels underground for the transportation of ore and the entry and exit of personnel. 2. Ore body detection: Detect the occurrence of ore bodies through drilling, geological exploration and other methods to determine the mining plan.Ore body detection: Detect the occurrence of ore bodies through drilling, geological exploration and other methods to determine the mining plan. 3. Ore mining: Explosion, tunneling and other methods are used to extract ore from underground. 4. Ore processing: Similar to open-pit mining, the excavated ore is crushed, screened, washed, and processed to obtain ore products that meet the requirements. E. Phosphate rock processing methods The processing of phosphate rock mainly includes the following steps: 1. Crushing: Crushing the raw ore to a particle size suitable for further processing. 2. Grinding: Grind the crushed ore to make it finer and increase the surface area for subsequent mineral processing. 3. Sorting: Use manual or machine methods to separate the crushed ore into good ore and impurities according to the surface characteristics of the ore. 4. Flotation: The ground ore is placed in a flotation tank together with a flotation agent. The ore and the flotation agent are adsorbed by bubbles, thereby separating the ore from impurities. 5. Desliming: Desliming the ore after flotation to remove the mud and impurities generated during the flotation process. 6. Concentrate treatment: The desludged ore is concentrated to improve the grade of the ore. 7. Tailings treatment: The tailings after concentrate treatment are treated to recover useful minerals or to carry out environmentally friendly treatment.

Overview of photoelectric sorting technology Photoelectric sorting technology is a technology that uses optical principles to automatically identify and classify materials. It detects the optical properties of materials, such as color, gloss, transparency, etc., through photoelectric sensors, and then determines whether it has the required characteristics through preset intelligent algorithms, and performs corresponding separation processing. This technology is widely used in industries such as mining, agriculture, food processing, and waste material recycling, especially in improving sorting efficiency and accuracy, reducing labor intensity, and reducing environmental pollution. Working principle of photoelectric sorting technology The working principle of photoelectric sorting technology involves several key components: light source system, sensor system, signal processing system, and execution system. First, the light source system provides light of different wavelengths to illuminate the material to be detected, so that the reflected light presents different colors. The sensor system, usually a linear array CCD sensor, captures these lights and converts them into electrical signals. The signal processing system processes these electrical signals, analyzes the characteristics of the materials through image processing algorithms, and classifies them according to preset standards. Finally, the execution system sorts the sorted materials, usually by high-speed airflow or robotic arms to exclude defective products and retain high-quality products. Application of photoelectric sorting technology in mining In the mining field, photoelectric sorting technology is mainly used for pre-sorting of ore to improve the overall grade of ore and reduce the cost of subsequent processing. For example, in the process of phosphate ore sorting, photoelectric sorting technology can effectively identify and remove low-grade ore and debris, thereby improving the efficiency of mineral processing and reducing energy consumption. In addition, this technology can also be used to process phosphate resources with fine particle size and complex embedded morphology, so that resources that were originally difficult to develop and utilize economically and efficiently can be fully utilized. Advantages and challenges of photoelectric sorting technology The advantages of photoelectric sorting technology lie in its high precision, high efficiency and environmental protection characteristics. It can complete the sorting of a large number of materials in a short time without adding chemical reagents, reducing pollution to the environment. However, the technology also faces some challenges, such as adapting to the sorting needs of more types and complex ore structures, improving the stability and anti-interference ability of the system, and reducing costs. Future development of photoelectric sorting technology With the continuous advancement of technology, photoelectric sorting technology is expected to further improve recognition accuracy and stability in the future, expand the scope of application, and play a greater role in mining and other fields. For example, by combining technologies such as artificial intelligence and big data analysis, the photoelectric sorting system will become more intelligent and automated, and can better adapt to different working environments and sorting requirements.

Potassium feldspar is a common feldspar mineral with the chemical formula NaAlSi3O8, belonging to the category of sodium aluminum silicate. It usually appears as glassy crystals and can be colorless, white, yellow, red or black. Potassium feldspar is most common in pegmatites and felsic igneous rocks such as granite, and is also found in low-grade metamorphic rocks and some sedimentary rocks. The hardness of potassium feldspar is about 6-6.5, the density is between 2.61-2.64 g/cm³, and the melting point is about 1100℃. Its theoretical chemical composition is Na2O: 11.8%, Al2O3: 19.4%, SiO2: 68.8%, but this theoretical value is difficult to achieve in nature. The classification of potassium feldspar usually based on its chemical composition and crystal structure. According to the chemical composition, potassium feldspar can be divided into different subspecies, such as albite, oligoclase and bytownite.

It can increase the alumina content in the glass mixture, reduce the melting temperature, and adjust the viscosity and chemical composition of the glass. In addition, potassium feldspar is also used in the chemical industry, abrasives and tools, welding rods and other industries. For example, it can be used as a raw material for enamel, the main raw material for refractory materials, and as a filler in detergents, toothpaste, cosmetics and other industries. The purity of potassium feldspar directly affects its application effect in industrial production. For example, in the ceramic industry, high-purity potassium feldspar can significantly reduce the firing temperature and improve the quality and performance of the product. Therefore, accurately judging the purity of potassium feldspar is of great significance to ensure product quality and production efficiency. The determination of potassium feldspar purity usually involves the following aspects: Chemical composition analysis: Through chemical analysis methods such as ICP, XRF, AAS, etc., the main components of potassium feldspar, such as SiO2, Al2O3, Fe2O3, TiO2, K2O and Na2O, can be accurately determined. The content of these components directly reflects the purity of potassium feldspar. Physical property test: Including tests of physical properties such as hardness, density, melting point, etc., these properties can also indirectly reflect the purity of potassium feldspar. Mineral composition analysis: Through methods such as X-ray diffraction (XRD), the mineral type and content of potassium feldspar can be determined, which is also a method to judge purity. The main method of impurity separation Flotation method: By adding different flotation agents, the surface properties of potassium feldspar and other impurity minerals are changed, thereby achieving separation. Magnetic separation: Separate iron-containing impurities from potassium feldspar by using magnetic differences.

Wollastonite surrounding rocks are divided into two types: marble type and skarn type. Among them, skarn type is mainly lens-shaped, cystic, irregular banded, etc., among which wollastonite generally has high iron impurities, and the gangue is mainly garnet, diopside, calcite and quartz. Garnet and diopside are separated by strong magnetic separation, and calcite and quartz are separated by flotation. The marble type is more complex, mainly in agglomerate and cystic shapes. Its wollastonite is distributed in flower and worm strips, with low iron content. The gangue is mainly calcite and quartz and a small amount of diopside. This type of ore is mainly separated by flotation to separate calcite and quartz. Wollastonite ore dressing and purification method At present, there are mainly manual selection, flotation, single magnetic separation, magnetic separation-flotation (electrical separation) for wollastonite separation. The purpose of wollastonite separation is mainly to reduce the iron content and separate calcite and waste rock. Hand selection mainly involves manually selecting rich ores or manually selecting rich wollastonite through conveyor belts. It is mainly suitable for ores with high wollastonite content. Flotation mainly involves separating wollastonite and calcite based on their different physical and chemical properties. It can also remove a large amount of iron impurities and improve the grade of wollastonite. Single magnetic separation mainly involves using weakly magnetic minerals such as garnet and diopside in the original ore. Wollastonite is not magnetic. Wollastonite is separated from other gangues through dry or wet strong magnetic separation technology. It can also remove a large amount of iron-containing ores and improve the overall grade. Magnetic separation-flotation is mainly suitable for the treatment of low-grade wollastonite. First, weakly magnetic ores are separated through magnetic separation, and then wollastonite is separated from quartz and calcite through flotation. The latest sorting method for wollastonite ore dressing - artificial intelligence photoelectric sorting Through physical sorting, the surface characteristics of wollastonite, calcite, and miscellaneous stones are used for sorting. Before entering flotation or magnetic separation, the raw ore is crushed and washed before entering the artificial intelligence sorting machine. Artificial intelligence photoelectric sorting uses the surface characteristics of wollastonite, calcite, quartz, garnet, and miscellaneous stones for sorting. The main surface characteristics of the sorting are color, color, texture, shape, etc., and the data model is established through artificial intelligence. The purpose of accurately sorting out wollastonite and associated stones is achieved. Artificial intelligence ore sorting machines are different from traditional photoelectric color sorters. Traditional photoelectric color sorters can only sort by color differences. For example, when the associated quartz or other colors are close to wollastonite waste rocks, the color sorter cannot accurately sort out wollastonite. Only artificial intelligence ore sorting machines integrate the multi-dimensional characteristics of good and bad materials in the raw ore, establish a sorting model, and achieve final sorting accuracy and low carryout of good and bad materials through artificial intelligence technology. https://www.mdoresorting.com/mingde-ai-sorting-machine-separate-quartzmicafeldspar-from-pegmatite Project Advantages Artificial intelligence can completely replace manual selection in the application of wollastonite. If the dissociation degree of wollastonite is good, the artificial intelligence machine can directly sort out wollastonite and tailings, which has the advantages of high efficiency, good effect and low cost. The cost is mainly the one-time equipment purchase cost and the subsequent equipment power supply cost. If the dissociation degree is average, the artificial intelligence machine can also sort out the wollastonite with good grade, or discard the useless waste rock, which can directly reduce the amount of ore entering magnetic separation or flotation, save the cost of magnetic separation and flotation, and reduce the processing level of tailings. In particular, Mingde Optoelectronics Artificial Intelligence Sorting Machine has been widely used in various ore sorting fields at this stage, not only in wollastonite. As long as there are ores with visible surface differences, they are within the sorting range of artificial intelligence sorting machines. The equipment has withstood the test of various industrial and mining enterprises in terms of technical maturity and actual application effect.

As the number of ore resources with low mining difficulty and good quality is decreasing, mining companies are gradually falling into trouble, especially low-grade mining companies. How to improve the economic value of mines? Reduce the overall mining and selection costs? It is an important problem facing its development, especially at the current stage, the mining and selection technology and production process improvements of industrial and mining enterprises are in a stagnant stage. The only best choice is to break the existing thinking mode. In view of the current situation of industrial and mining enterprises, there will be no major breakthroughs in mining and selection technology for the time being. Only by looking for external breakthroughs in the production process can new innovations be achieved. It is obvious that the best solution is to start with the sorting after the crushing and dissociation of the original ore. Some people will definitely ask why? In fact, it is very simple. We need to understand what ore sorting is and what is the difference between the sorting mentioned and the sorting at the current stage. The ore sorting mentioned here is to enrich the grade of the ore in advance before grinding and crushing, and to raise the pre-throwing waste tailings to reduce the amount of ore entering the subsequent process, saving a lot of costs for the subsequent process. At the same time, the pre-throwing waste tailings have not been ground and have certain economic value. Take an example of economic benefits. Let's do some economic calculations. Assuming that an industrial and mining enterprise mines 1 million tons per year, before using an ore sorter, the original production process is mining-crushing-grinding-flotation. According to the calculation of $6.3 per ton for grinding and flotation, the annual cost before using an ore sorter is about 6.3 million dollar. After using an ore sorter, each ore sorter sorts about 25 tons per hour (the smaller the particle size, the lower the hourly sorting output. In this example, the particle size of the ore particles is in the range of 1cm-4cm). The sorting cost is mainly electricity. The electricity cost per machine is $1.37 per hour, and the sorting cost per ton is about $0.137. According to 20% of the discarded tailings, there is no need for subsequent grinding and flotation, and the annual savings can reach about 1.1 million dollar. In addition, the discarded tailings can still be backfilled in the mine, or sold as other construction, road construction and other materials. The overall estimated annual output value is at least more than 1.37 million dollar. Among them, Mingde Optoelectronics' artificial intelligence ore sorter was born. Committed to the introduction, research and development, promotion and application of artificial intelligence ore sorting technology. AI Ore Sorting Machine AI Ore Sorting Machine is a device that uses the principle of photoelectric sorting, artificial intelligence means, and AI photoelectric sorting technology. After the original ore is crushed and before flotation, it can be sorted in a composite manner according to the different surface characteristics of the original ore, such as texture, color, texture, shape and other multi-dimensional characteristics, to achieve ore grade enrichment and pre-disposal of tailings.
