This solution realizes the intelligent controllable sorting of the machine through the combination of software and hardware, improves the limited sorting materials, and expands the sorting and use scenarios. The scope of sorting has broken through from color sorting to the sorting of minerals with multi-dimensional feature differences. The specific workflow of the intelligent sorting solution is as follows: First, the personnel will confirm the good and bad materials, sort a number of good and bad materials manually, and collect and train images on the smart machine respectively, extract the surface texture, gloss, texture, state, color and other features of the ore and gangue to establish a sorting model.

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. Intelligent sorting equipment. It also has the following advantages https://www.mdoresorting.com/mingde-ai-sorting-machine-separate-quartzmicafeldspar-from-pegmatite Adjustable parameters: Sorting models can be established according to different sorting requirements to meet personalized sorting requirements; Automatic sorting: No manual work is required to achieve intelligent ore sorting with high sorting efficiency; Intelligent: It can continuously learn through the learning mode to further improve the overall sorting effect; Application range: Mainly in the sorting of talc, wollastonite, potassium feldspar, fluorite, quartz, calcite, lithium ore, gold ore, iron ore, lead-zinc ore, high-crystalline silicon and other ores with visible differences; Applicable fields: new and old mines, historically abandoned low-grade ores and other industrial and mining enterprises.

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.

Overview of silica ore Silica ore is a non-metallic mineral with silica-rich minerals as the main component, mainly including quartz sandstone, quartzite and other forms. The classification of silica ore is complex and diverse, and can be distinguished according to the environment, composition, structure, etc. of its formation. The application of silica is extremely wide, involving many industries such as glass, ceramics, and refractory materials. Classification and characteristics of silica ore The classification of silica ore can be divided from multiple angles: 1. Classification by organizational structure: It can be divided into crystalline silica and cemented silica. Crystalline silica is mainly composed of quartz particles, while cemented silica is quartz particles combined by siliceous cement. 2. Classification by transformation speed: Silica can be divided into four types according to its transformation speed at high temperature: extremely slow, slow, medium and fast transformation. 3. Classification by density: Silica can also be divided into extremely dense, dense, relatively porous and porous according to its density. Application of silica ore Due to its unique physical and chemical properties, silica ore has important applications in many fields: 1. Glass industry: silica ore is an important raw material for glass manufacturing, especially vein quartz, which is the preferred raw material for producing high-quality glass because of its SiO2 content of up to 99%. 2. Ceramic industry: silica ore is used to produce ceramics, especially some ceramic products with special requirements, such as electrical insulation porcelain, chemical corrosion-resistant porcelain, etc. 3. Refractory materials: The high temperature performance of silica ore makes it the preferred raw material for making refractory materials, such as blast furnace refractory materials used in steel smelting. 4. Abrasive industry: silica ore is also widely used in the abrasive industry. Due to its high hardness, it can be used in various grinding and polishing processes. Mining and ore dressing and purification of silica ore The mining of silica ore is mainly carried out in open-pit mode, and the ore dressing and purification process includes steps such as scrubbing, magnetic separation, flotation, acid leaching and photoelectric separation. These processes are designed to improve the purity of silica and reduce the impurity content to meet the specific needs of different industries. Crushing and Grinding Silica ore is usually crushed using jaw crushers and cone crushers. The former is suitable for primary crushing, while the latter is used for secondary or finer crushing. The crushed silica enters the grinding stage. Grinding equipment includes ball mills, high-pressure suspension roller mills and abrasive mills, etc. These equipment can grind silica to the required particle size and improve the quality of silica. Scrubbing and Magnetic Separation Scrubbing is the use of mechanical force and the abrasive force between sand particles to remove film iron, bonding and muddy impurity minerals on the surface of quartz sand. Magnetic separation can remove magnetic minerals such as hematite, limonite and other impurities from scrubbed silica to the maximum extent. Flotation Flotation is mainly used to remove non-magnetic associated impurity minerals such as feldspar, mica, etc. During the flotation process, the chemical conditions of the flotation environment are adjusted by adding flotation agents such as collectors, frothers and regulators to improve the separation efficiency of silica and impurities. Acid leaching Acid leaching is mainly used to further reduce the iron content in silica, especially for quartz sand with high purity requirements. Acid leaching can make the purity of silicon dioxide reach more than 99.93%. Photoelectric sorting https://www.mdoresorting.com/mingde-ai-sorting-machine-separate-quartzmicafeldspar-from-pegmatite Photoelectric sorting is a technology that uses the surface characteristics of silica ore for identification and sorting. It is suitable for silica ores with obvious or complex color characteristics. Through photoelectric detection technology, heterochromatic granular materials are automatically sorted out, thereby improving the overall quality of silica. It is worth mentioning that Mingde Optoelectronics Technology Co., Ltd. is the first to introduce artificial intelligence technology in the field of visible light photoelectric sorting, which can sort more categories of ores. In silica ore sorting, the color, gloss, texture and texture of the ore surface can be used to distinguish the silicon in the ore from the feldspar of the same color. The sorting effect is more accurate than that of the color sorter. Pre-sorting and auxiliary processes Pre-sorting usually includes processes such as scrubbing, magnetic separation and flotation, while auxiliary processes include adding pre-sorting processes after crushing, and improving the quality of the ore entering the mill through pre-waste treatment, improving the production efficiency of subsequent processes and reducing production costs. Conclusion In summary, silica ore, as an important non-metallic mineral, not only has a wide variety of types, but also has a wide range of industrial application value. The continuous deepening of research on its mining and purification technology will help to better realize its potential in various fields. With the advancement of science and technology, the utilization of silica ore in the future may be more efficient and environmentally friendly.

Enrichment is to separate valuable minerals from ore by physical, chemical or biological methods to improve their grade and recovery rate. Research progress of pretreatment technology The development trend of pretreatment technology is to improve efficiency and reduce costs while paying attention to environmental protection and sustainability. The high-pressure roller mill pretreatment technology in the crushing stage improves the dissociation degree and grinding efficiency of the ore through high pressure and slow relative movement. The pre-waste technology in the primary selection stage refers to separating a part of waste rock or low-grade ore in the early stage of ore processing to reduce energy consumption and cost in subsequent processing. For example, by pre-selecting and discarding waste, the amount of ore entering the subsequent process can be reduced, saving a lot of subsequent process costs. At the same time, the pre-discarded waste tailings can be used as building aggregates and mine backfill without grinding, which has certain economic value and environmental value. Through pretreatment and pre-selection, the grade of ore can be improved, the amount of ore entering the mill can be reduced, and the tailings can be discarded in advance, thereby improving resource utilization and reducing energy consumption and environmental pollution. Ore photoelectric sorting technology is an important branch of the current ore sorting field. It uses different physical properties of ore, such as color, texture, density, etc., to achieve effective ore sorting, which is of great significance for ore pretreatment. Research progress of enrichment technology Ore enrichment technology can increase the content of useful components in ore, thereby improving resource utilization. For example, through pretreatment and enrichment technology, the original low-grade ore can be made usable, the loss of mineral resources can be reduced, the import volume of mineral resources can be reduced, and the resource utilization of low-grade ore and stockpiled waste can be realized. Ore enrichment can also reduce the processing cost and energy consumption of ore. For example, through pre-enrichment technology, the amount of subsequent grinding-flotation ore processing can be reduced, production costs can be reduced, and the economic benefits of the enterprise can be improved. At the same time, ore enrichment technology also has extremely high environmental and social benefits. In terms of environmental effects, through scientific ore enrichment and ore deposit analysis, environmental pollution can be reduced, the ecological environment can be protected, resources can be recycled, and the service life of resources can be extended. In terms of social benefits, the innovation of ore enrichment technology has promoted the upgrading of the mining industry. The development of intelligent mineral processing technology, such as intelligent mineral processing and intelligent monitoring, has improved the efficiency and accuracy of mineral processing, reduced labor costs, and promoted the transformation of the mining industry towards high efficiency and environmental protection. On the other hand, through ore enrichment, employment opportunities can be increased and the living standards of local residents can be improved. Among them, photoelectric sorting is particularly representative in ore enrichment. By analyzing the surface characteristics of the ore to be processed, the ore is preliminarily sorted, thereby realizing pollution-free and efficient intelligent sorting. Photoelectric sorting has the advantages of high efficiency, low cost, and green environmental protection. It can save freight and reagent costs in the flotation link and extend the service life of the tailings pond. In addition, the mining boundary grade can be reduced and the amount of recoverable resources can be increased. https://www.mdoresorting.com/mingde-ai-sorting-machine-separate-quartzmicafeldspar-from-pegmatite Mingde Optoelectronics Technology Co., Ltd. is the first to introduce artificial intelligence and big data technology in the field of visible light photoelectric sorting, which broadens the adaptability of the machine and allows the photoelectric sorting machine to sort more types of ores.

These pioneering measures make our machines more suitable for mining companies and make ore sorting better and faster. Conclusion In summary, ore pretreatment and enrichment technology plays an important role in improving the utilization efficiency of mineral resources, reducing production costs, and promoting environmental protection and sustainable development. With the continuous emergence and application of new technologies, pretreatment and enrichment technology will continue to develop in the direction of high efficiency, environmental protection, and low cost, and contribute to the sustainable development of the mining industry.

Photoelectric sorting is an important ore sorting method in ore pre-sorting. Photoelectric sorting equipment is a device that directly completes the ore sorting process. During the ore sorting process, the sorting equipment identifies the ore through its physical characteristics, mainly through the differences in color, texture, texture, shape, gloss, density and other characteristics, to achieve the sorting of useful minerals and gangue minerals. At present, the commonly used mining sorting equipment mainly includes ore color sorters, artificial intelligence sorters, and X-ray intelligent sorters. Below, we will take you to understand each type of mining sorting equipment and its applicable scope one by one, and help you correctly choose the appropriate sorting equipment. 1. Ore color sorter Ore color sorter is mainly based on the color difference of materials. It integrates optical, mechanical and electrical equipment to achieve material sorting and purification through photoelectric detection and image processing. It belongs to a color sorting ore sorter. This type of ore color sorter integrates high technologies such as light, machinery, electricity, and gas. It is widely used in material sorting to improve the quality of material products. In recent years, domestic color sorters have continuously accelerated the pace of technological innovation. Manufacturers have grown through exploration and innovation, key components have been updated, and first-line products have become increasingly mature in terms of stability, reliability, and high-precision sorting effects. The ore color sorter mainly includes a vibrating bucket, a main unit for integrated feeding, sorting and unloading, and a touch-sensitive operation panel. When working, the ore enters the crawler through the color sorter feeding hopper and is quickly transported into the sorting box. Each ore is scanned line by line through two sets of high-definition cameras, and the relevant information is transmitted to the central system through the sensor. The central system compares the wavelength or frequency of the different colors of reflected light waves of superior and inferior ores with the set parameters, and then identifies the location of the heterochromatic ore to be removed through a complex algorithm, and issues instructions to the corresponding solenoid valve, using pneumatic force for precise separation. The ore color sorter has a wide range of applications, mainly for minerals with color differences, such as quartz, calcium carbonate, barite, calcite, dolomite, potassium feldspar, wollastonite, fluorite, tungsten ore and other minerals. 2. Artificial Intelligence Sorting Machine The artificial intelligence sorting machine mainly relies on AI photoelectric sorting machine technology, and uses artificial intelligence, deep learning, big data and image visual enhancement technology to identify and sort ore. This type of sorting equipment uses artificial intelligence technology to break the original color sorting material limitation problem, greatly expand the sorting application scenario, and meet the sorting use of some difficult and complex ores. The equipment is mainly composed of a vibrating bucket, a host and a microcomputer operation platform. When working, it is necessary to manually sort a number of useful minerals and gangue minerals, and perform image acquisition and training on the artificial intelligence machine respectively. The equipment will automatically extract the surface texture, gloss, texture, shape, color and other features of useful minerals and gangue minerals to establish a sorting model. During the sorting process, the ore enters the crawler through the intelligent machine feed hopper, and enters the sorting box after rapid transportation. The upper and lower sets of ultra-high-definition cameras will perform multi-dimensional stereoscopic scanning on each ore material, and transmit the information of each ore material from the sensor to the industrial computer. It identifies useful minerals and gangue minerals through model recognition and algorithms, and issues instructions to the solenoid valve corresponding to the gangue area, using pneumatic force for precise separation. The equipment is mainly trained and modeled based on the multi-dimensional characteristics of the surface of the ore, and then identified and separated. The equipment can be adjusted according to the on-site situation, and can achieve diversified ore sorting. Artificial intelligence sorting machines are suitable for complex and difficult-to-sort minerals. As long as the ore has surface texture, gloss, texture, shape, color and other surface characteristics, it can be sorted, such as pebbles, silica, wollastonite, silicon slag, gold ore, talc, phosphate ore, coal-based kaolinite, fluorite, lithium ore and other ores. The overall sorting and accuracy and adaptability are far superior to traditional color sorters. 3. X-ray intelligent sorting machine X-ray intelligent sorting machine is mainly XRT (transmission technology), which detects the characteristic values ​​of ore size, thickness, density and the difference in the reaction of elements and atomic sequences of related components to X-rays through X-rays to achieve mine waste separation. This technology is mainly suitable for metal ores that cannot be manually sorted due to surface characteristics. Its operating principle: the ore and gangue to be sorted must have obvious differences in density. The specific process is as follows: First, a small amount of ore and gangue should be taken for training. The different densities make X-rays absorb different degrees when transmitting ore and gangue. Then the camera is used to collect and transmit. The grayscale value of the image is different after industrial computer imaging and algorithm. The deep learning model is built. When the X-ray machine is produced, the feeding system will enter the detection area at high speed from the crawler. The x-ray will transmit each ore and gangue. The self-developed multi-channel high-definition camera is successively used for signal acquisition and transmission to the industrial computer. It uses complex algorithms and image processing, and then compares and identifies with the parameters of the established model. The industrial computer will issue instructions to the gas valve at the corresponding position of the gangue, and use pneumatic force to separate the gangue to achieve the purpose of waste disposal and enrichment. X-ray intelligent sorting machine is suitable for ores with density differences such as coal gangue, lead-zinc, tin, antimony, tungsten, copper, manganese, titanium, fluorite and other metal and non-metallic ores.

Overview Pegmatite quartz refers to high-purity quartz formed in pegmatite. Pegmatite is a special granite rock, usually composed of coarse to huge quartz crystals. The quartz in these rocks usually has a larger crystal size and a lower impurity content. Formation process of pegmatite quartz The formation of pegmatite quartz is a complex process inside the earth, involving many geological processes such as magmatic activity, metamorphism, and tectonic movement. Next, we will discuss this process in detail from different angles. Magmatic activity and the formation of pegmatite quartz The formation of pegmatite quartz is closely related to magmatic activity. During the intrusion evolution of magma, due to changes in temperature, pressure and other conditions, hydrothermal fluids rich in SiO2 are differentiated. These hydrothermal fluids penetrate into the surrounding metamorphic rock system along the bedding and cracks, or invade along the contact fracture zone of the previous magmatic rock to form vein quartz ore bodies. Metamorphism and the formation of pegmatite quartz The hydrothermal fluid produced by regional metamorphism or mixed lithification is also an important factor in the formation of pegmatite quartz. Strong magmatic activity and tectonic movement provide heat sources for metamorphism. When water-containing igneous rocks and basement protoliths are metamorphosed, a large amount of water is released to form metamorphic hydrothermal fluids. These ore-bearing solutions migrate along the ductile shear zone under the action of tectonic stress. Due to changes in temperature and pressure conditions, SiO2 is supersaturated and deposited to form vein quartz. Tectonic environment and the formation of pegmatite quartz The formation of pegmatite quartz is closely related to a specific tectonic environment. For example, pegmatite deposits are formed in a stable tectonic environment at the top of granite, formed by the recrystallization of the surrounding granite and the decomposition of the mineral components that make up the granite. Details of the formation of pegmatite quartz The details of the formation of pegmatite quartz can be revealed by studying the fluid inclusions inside it. Fluid inclusion microscopic analysis shows that in the process of wall crystallization, the brine H2O-NaCL-KCL-(CO2,N2) type fluid (about 20wt.% NaCL and about 3wt.% KCL) is saturated, and in the process of magmatic hydrothermal crystallization, multiphase cassiterite mineralization forms large microcline crystals in the wall belt, and is combined with quartz, F-poor black mountain rock, and carbonate- and boron-rich manganese fluoroapatite in the core area.

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.
