Industrial silicon production is based on silica as raw material and carbonaceous raw material as reducing agent, which is smelted by electric furnace. Among them, industrial silicon is mainly used as raw material for polysilicon, monocrystalline silicon, silicon alloy, and organic silicon, with applications in aerospace, new energy, high-purity semiconductor and other industries, and the demand is increasing year by year. Industrial silicon in the process of smelting refined silicon in the average refining 1 ton of silicon water produces about 100 kg of silicon slag, so the number of industrial silicon slag produced each year is huge, for a long time silicon slag is used to pave the road or as a waste pile, not only occupy a lot of land resources, but also bring a series of environmental problems. At the same time, industrial silicon slag contains more than 15% of monomeric silicon, which is not utilized, resulting in a waste of silicon resources and bringing great economic losses to enterprises. In addition, there is also heavy adulterated silicon material in silicon waste that has been mixed with impurities such as B, P, Ga, Al, etc. In order to enhance utilization, it is also necessary to sort out the available silicon.   Industrial Silicon Smelting   Currently. For industrial silicon slag and mixed silicon waste processing methods are mainly manual sorting, re-sorting process, electromagnetic induction melting or back to the furnace re-refining way, which manual sorting by crushing large silicon waste, from which large particles of industrial silicon for recycling, the overall sorting efficiency is low, after sorting there are more high content of industrial silicon can not be recycled; re-election process requires the silicon slag grinding to a few millimeters, the process is complex, and also waste a lot of water. Also wastes a lot of water, and the separation effect is relatively general; electromagnetic induction melting or furnace melting, because of high energy consumption and silicon slag viscosity, it is difficult to directly separate out.   The existing recycling process of industrial silicon have certain problems, but the application of the latest sorting technology of artificial intelligence sorting machine, in the sorting can replace the existing silicon slag sorting process, to provide a simple and efficient sorting method, and enhance the industrial silicon recycling rate in silicon slag. The silicon slag only need to crush, Use artificial intelligence machine sorting directly, in the silicon slag recovery of industrial silicon sorting precision, sorting effect, sorting efficiency, recovery rate, recovery costs are better than the existing silicon slag sorting process.   The main working principle is that the silicon slag is crushed and dissociated, and the difference in surface characteristics between the slag and industrial silicon is used to identify good and bad materials through photoelectric sorting technology,Optical sorting machine, and the good and bad materials are sorted out through the control system controlling the spray valve, so as to achieve the sorting separation of silicon slag and industrial silicon.     Before sorting   After sorting   At the same time, the artificial intelligence sorting machine has a great improvement in sorting compared with the ore color sorting machine, which can only judge good and bad materials based on color. In the silicon slag sorting, there is a coexistence of good and bad materials, small color differences, it can not identify the good and bad materials by color, artificial intelligence machine will not worry about this problem, through the identification of multi-dimensional characteristics of silicon slag,it establish the models, accurately identify materials with good sorting effect. So as to achieve the purpose of high-efficiency recycling of industrial silicon and increase the economic benefits of enterprises.   As a high-tech enterprise specializing in industrial ore sorting, Mingde Optoelectronics has mature technology accumulation for solving all kinds of industrial ore sorting problems and bulk ore sorting system, and the product application scope covers talc, fluorite, wollastonite, potassium feldspar, barite, quartzite, calcite, calcium carbonate, magnesite, lithium pyroxene, phosphate ore, gold ore, pebbles, quartz sand, coal gangue, vanadium ore and nearly 100 kinds of metal and non-metal. We have strong technical advantages in the field of ore sorting. The Preconcentration and discarding sorting machine will achieve the rapid accumulation of wealth.   Edited by Jacky 

Lead zinc ore refers to the mineral resources rich in metal elements lead and zinc. In nature, lead and zinc often coexist, and are also associated with other metal ores and gangue ores. The metal ores mainly include brass, pyrite, etc. The gangue ores mainly include quartz, calcite, fluorite, barite, dolomite, etc. According to oxidation, it can be divided into oxidized ores and sulfide ores. Because lead-zinc ores have strong sulfur affinity, most lead-zinc ores in nature are sulfide ores. The main application fields are machinery, military, metallurgy, chemistry and medicine. The domestic lead and zinc mineral resources are relatively rich, which are characterized by wide distribution and high concentration of mineral resources in 27 provinces, cities and districts in China. From the perspective of enrichment and existing reserves, China's lead and zinc ores are mainly distributed in Inner Mongolia, Gansu, Hunan, Yunnan, Guangxi and Guangdong, accounting for 64% of the national lead and zinc ore reserves; Large and medium-sized deposit stations have high reserves and complex ore types. The reserves of lead and zinc in large and medium-sized deposits account for 72% and 88.4% respectively. There are few single type lead or zinc ores, and the ore types are relatively complex, mainly including lead zinc ores, lead zinc copper ores, lead tin ores, lead antimony ores, etc; There are many poor ores, few rich ores and few easy beneficiation. According to statistics, the domestic lead and zinc ores are mostly of 5% - 10% grade, and those with a grade higher than 10% only account for 15% of the total storage, while the foreign lead and zinc ores have a higher overall grade, most of which are more than 10%. The types of lead-zinc deposits in China mainly include granite type, skarn type, porphyry type, marine volcanic rock type, continental volcanic rock type, carbonate rock type, mudstone fine clastic rock type and glutenite type. In terms of beneficiation process, the lead-zinc ore is mainly flotation, and gravity concentration is also used. At the same time, the internal distribution of lead-zinc ore is uneven. There are different separation processes for each ore. The common separation processes of lead-zinc ores in China mainly include preferential flotation, mixed flotation, full mixed flotation, heavy medium pre separation, heavy medium pre separation flotation gravity separation combination, etc. floatable flotation and asynchronous mixed flotation. The above sorting methods of lead and zinc ores belong to conventional traditional separation methods, but at present, China's lead and zinc industry is mainly faced with several problems. The contradiction between industrial sustainable development and ecological environment protection is mainly reflected in China's long-term high demand for lead and zinc ores, driving the rapid development of lead and zinc industry, causing certain impact and damage to the ecological environment, and the low comprehensive utilization of lead and zinc resources, Especially in the aspect of valuable associated gangue, at the same time, strict prevention of heavy metal pollution has become an insurmountable red line in the lead and zinc industry. The way of scale, volume and extensive development in the lead and zinc industry has not met the development needs at this stage. At this stage, it is necessary to change to a circular, low-carbon and green direction. Another important reason is that the production cost of lead-zinc ore has risen and the product price has fallen, and the cost rigidity has risen - the equipment has low operating rate - the supply is relatively surplus - the price has low volatility - the benefit has been marginalized ". At the present stage, the requirements for lead and zinc ore mining and beneficiation are to meet the needs of social development, improve the comprehensive utilization of resources, reduce production costs. Green and sustainable development is the new trend of the industry, especially in the continuous use of lead and zinc beneficiation process, which is obvious. For some lead and zinc ore beneficiation stages, we can fully take measures to increase the economic benefits of the mine, save the beneficiation cost and reduce the tailings disposal capacity, It also meets the development needs of green mines. The main plan is to enrich the grade of lead-zinc ore in advance, pre dispose the waste tailings, and reduce the processing capacity of grinding flotation raw ore, mainly using the photoelectric separation equipment ore separator. There are mainly two types of ore separation equipment suitable for the separation of lead and zinc ores. One is the Mingde Optoelectronics artificial intelligent ore separator, which establishes a multidimensional three-dimensional model of ores through the surface characteristics difference after the lead and zinc ores are broken and separated, and identifies the good and bad materials, so as to achieve the purpose of grade enrichment. For example, lead and zinc barite, lead and zinc fluorite ores, etc., the expected beneficiation effect can be achieved through the artificial intelligent ore separator. The second one is X-ray intelligent ore separator, which mainly uses X-ray to project lead-zinc ore and identify the good and bad materials according to the difference of ore density, so as to achieve the purpose of enrichment. The above two ore separators can meet the development needs of the lead-zinc industry at this stage.   Among them, Mingde Optoelectronics focuses on the field of ore separation and digital color separating machine. It has accumulated rich experience and technology in ore photoelectric separation and precipitation. The four series of products designed and produced not only have a development prospect in the lead and zinc industry, but also have a large application space in other ore separation and beneficiation fields. At this stage, the application scope covers the metal and non-metallic fields, such as fluorite, talc, quartzite, barite, K-feldspar, calcium carbonate, magnesite, gold mine There are nearly 100 kinds of ores such as high crystal silicon, copper, iron, vanadium, phosphate rock, coal and gangue.    

Wollastonite wall rocks are divided into marble type and skarn type. The skarn type is mainly lenticular, vesicular and irregular banded. The iron impurities in the wollastonite are generally high. 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 relatively complex, mainly in the form of lumps and sacs. The wollastonite is distributed in the form of flowers and worm stripes, with low iron content. The gangue is mainly calcite and quartz and a small amount of diopside. This type of mineral is mainly separated by flotation, and calcite and quartz are separated. Wollastonite Beneficiation and purification method of wollastonite At present, the separation of wollastonite mainly includes manual separation, flotation, single magnetic separation, magnetic separation flotation (electric separation). The purpose of wollastonite beneficiation is mainly to reduce iron content and separate calcite and waste rock. Manual separation mainly refers to manual selection of rich ore or manual selection of rich ore wollastonite through conveyor belt, which is mainly applicable to ores with high wollastonite content. Flotation is mainly based on the difference of physical and chemical properties on the surface of wollastonite and calcite. Flotation can effectively separate them, remove a large number of iron impurities, and improve the grade of wollastonite. Single magnetic separation mainly uses weak magnetic minerals such as garnet and diopside in the raw ore, and wollastonite is not magnetic. Through dry or wet strong magnetic separation technology, wollastonite and other gangue can be separated, which can also remove a large amount of iron ore and improve the overall grade. Magnetic separation flotation is mainly applicable to the treatment of low-grade wollastonite. First, weakly magnetic ores are separated by magnetic separation, and then wollastonite is separated from quartzite and calcite by flotation. The latest separation method of wollastonite beneficiation - artificial intelligent photoelectric separation Through physical separation, wollastonite, calcite, miscellaneous stone and other surface characteristics are used for separation. Before flotation or magnetic separation, raw ore is crushed and washed before entering the artificial intelligent separator. Artificial intelligence photoelectric sorting uses surface features such as wollastonite, calcite, quartz, garnet seed stone, and miscellaneous stone to sort, judge the difference of various surface features such as color, color, texture, and shape, and establish a data model by means of artificial intelligence. To achieve the goal of precise separation of wollastonite and associated stone. The artificial intelligent ore separator is also different from the traditional photoelectric color separator. The traditional photoelectric color separator can only separate by color difference. For example, when the associated quartz or other colors are close to the waste wollastonite, the color separator cannot accurately separate the wollastonite. Only the artificial intelligence ore separator can establish the separation model based on the multi-dimensional characteristics of good and bad materials in the raw ore, and achieve the final separation accuracy and bring out the good and bad materials with low yield through the artificial intelligence technology. Project advantages In the application of artificial intelligence in wollastonite, it can completely replace manual selection. If the wollastonite is well dissociated, the artificial intelligence machine can directly separate the wollastonite and tailings, which has the advantages of high efficiency, good effect and low cost. The cost is mainly the one-time equipment procurement cost and the subsequent equipment power supply cost. If the degree of dissociation is general, the ore with good wollastonite grade can also be separated by the artificial intelligence machine, or the useless waste rock can be discarded, which can directly reduce the amount of ore entering the magnetic separation or flotation, save the cost of magnetic separation and flotation, and reduce the treatment level of tailings. In particular, Mingde Optoelectronics artificial intelligent sorter has been widely used in various ore sorting fields at this stage, not only in wollastonite, but also in ores with visible differences, both in the scope of artificial intelligent sorter. The equipment has withstood the test of various industrial and mining enterprises in terms of technical maturity and practical application effect.

Gold ore from the major classification is mainly for the vein gold deposits and alluvial gold deposits two types, which vein gold ore is the main case of internal geological action, mainly by volcanic, magmatic, geological action to form; alluvial gold deposits mainly by the mountain gold ore exposed in the ground, after long-term weathering, exfoliation, broken into gold sand, gold particles, gold flakes, gold froth, in the wind and water transport action gathered, deposited in the river, lake, coast, the formation of flood type, alluvial type or Coastal type alluvial gold deposits; There is another part after weathering and denudation, forming residual type alluvial gold deposits or slope accumulation type alluvial gold deposits, this kind of ore formation is generally more long time. According to the associated situation of China's gold ore types can also be divided into gold quartz veins, gold pyrite quartz veins, gold pyrite alteration granite, gold polymetallic sulphide ore vein type, gold oxide ore vein type and gold tungsten arsenic ore vein type.   Vein gold ore industrial mining grade generally in 3 ~ 5 g / ton, border grade 1 ~ 2 g / ton, alluvial gold in 0.2 ~ 0.3 g / cubic meter, border grade 0.05 ~ 0.1 g / cubic meter, but the current stage of mining gold ore in China mainly to vein gold deposits, accounting for about 75% ~ 85%.   At this stage, gold ore is widely used in jewelry, industrial, high-tech industries, etc. Because of its scarcity and non-renewable, the overall value is high. At this stage, gold ore beneficiation methods are mainly divided into four kinds: heavy separation method, flotation method , chemical separation method, and photoelectric separation method.   The re-election method is suitable for coarse-grained gold recovery, and generally belongs to the auxiliary process in gold ore beneficiation, placed in flotation or chemical sorting before as pre-selection process.   Flotation method is mainly widely used in rock deposits, the process has suction type or inflatable agitation type flotation machine for flotation.   Chemical separation method mainly has amalgamation and chlorination method, amalgamation method is mainly applicable to coarse grain monomer gold applicable, but because of its pollution, gradually be replaced, chlorination method mainly has two kinds of stirring chlorination and percolation chlorination.   The above three sorting are conventional gold ore sorting, with economic mining grade or higher than the industrial grade of gold ore, sorting cost is lower than the economic cost, but the general situation of China's gold ore rich ore less poor ore more; mining difficulty, easy to mine less difficult to mine more, most of the gold ore grade is less than 2 g / ton, belong to or lower than the critical mining grade, using the above way directly sorting, more gold ore sorting will appear below the economic mining Value.   Photoelectric sorting method grasps the pain and difficulty of domestic gold ore sorting, and uses artificial intelligence + photoelectric sorting means to enrich gold ore by pre-throwing waste to achieve higher economic mining grade, which solves the problem of low grade and high sorting cost of domestic gold ore. The working principle is mainly to crush and dissociate the original gold ore, after the artificial intelligence sorting machine to establish a multi-dimensional model of the ore, the use of AI photoelectric sorting machine technology to identify the texture, color, luster, shape, reflectivity and other comprehensive characteristics of the gold ore surface differences, after the industrial computer with artificial intelligence technology to sort out the gold ore concentrate and waste rock, so as to achieve the purpose of gold enrichment.     After the artificial intelligence ore sorting machine of the original ore, the ore particle size requirements, only the normal crushing and dissociation, particle size in 0.5cm-10cm, size with the selected particle size in 3-4 times, can be directly sorted enrichment, which throw waste tailings can be used as various types of construction, mine backfill and other materials. After the enrichment of gold ore after flotation or chemical separation method, sorting out the gold ore, pre-throwing waste reduces the processing level of the original ore, saving the processing cost of the subsequent processes.   For some gold ore below the economic mining grade, through the artificial intelligence ore sorter, can be enriched to reach the economic mining grade, enhance the use value of a large number of low-grade gold ore mine, artificial intelligence sorter is not only able to sort gold ore, for gold ore associated ore, as long as it can be broken and dissociated, can use artificial intelligence machine for sorting, enhance the comprehensive utilization rate of the mine, at the same time artificial intelligence sorter equipment The cost itself     Mingde photoelectric artificial intelligence ore sorting machine, for gold ore sorting has mature technology accumulation, can enrich gold ore under the premise of pre-throw waste tailings, and throw waste tailings gold grade is much lower than the economic mining grade.  

Coal gangue as a coal mining process produced in the largest number of industrial solid waste, improper handling will cause some damage to the environment and pollution, and in the process of dealing with coal gangue because of its large processing level, low economic benefits, is a more headache for coal mining enterprises. According to the statistics of the relevant departments, the current coal gangue stockpile amounted to more than 3 billion tons, of which the coal system in order to discharge nearly 100 million tons of coal gangue growth each year. Different across the country because of coal storage and production, there are big differences in the coal gangue treatment process policy, to the coal province of Shanxi, for example, coal enterprises mining process generated by the coal gangue, because of its great amount, as construction materials, road construction, etc. The supply far exceeds the demand, resulting in coal enterprises coal gangue treatment is still a huge problem. Among them, coal gangue as coal mining, washing and other aspects of solid waste, in which there are also associated minerals with economic mining grade, mainly because of its sorting difficulty, sorting costs and other factors. The vast majority of them are still treated in a simple and crude way, resulting in low socio-economic benefits of coal gangue. In order to respond to such needs, we Mingde Optoelectronics launched an X-ray artificial intelligence sorting machine. X-ray intelligent sorting machine, can be pre-precision throwing waste - advance sorting of high-grade gangue associated ore, to achieve economic mining grade, directly increase enterprise revenue, significantly reduce the amount of gangue into the "research - grinding - crushing The amount of gangue into the "research-grinding-crushing" process, effectively throw away the waste rock in the gangue, reduce the amount of gangue processing and processing costs, indirectly improve the comprehensive benefits of the original mine, but also reduce the pollution of the environment and the generation of tailings, to achieve the maximum use of resources, waste into treasure, but also in line with the national green mine development direction.   Hefei Mingde Optoelectronics Technology Co.   Founded in 2014, is a national high-tech enterprise specialized in visible light, intelligent sorting technology and X-ray overall solution for industrial and mining industry.

Potassium feldspar is also known as orthoclase, the color is usually red flesh red, yellowish white, in addition to orthoclase there are also perovskite and triclinic crystal system. Usually density in 2.54-2.57g/cm³, abrasive materials and other industrial sectors and the production of potash fertilizer with. Among them in the ceramic industry as embryo ingredients, glaze dosage accounted for 30%, the rest are mostly used in chemical, glass, glass fiber and other industries, with the development of China's social and economic development, the increasing demand, potassium feldspar application prospects are more promising. The main problem of domestic potassium feldspar at this stage, rich in resources, potassium feldspar is mostly symbiotic with quartz, but also with iron-bearing minerals, mica, clay minerals and rutile. In order to improve the industrial value of potassium feldspar, its beneficiation and removal of miscellaneous stones is essential, especially the domestic potassium feldspar contains excessive iron, iron removal is the key to purification.        Next, a brief description of how to remove potassium feldspar and beneficiation equipment process flow. Photoelectric Separation and Removal      Potassium feldspar photoelectric sorting and debris removal, mainly is the original potassium feldspar ore after coarse break or second break associated ore can be sorted and dissociated, the use of photoelectric sorting equipment pre-throw waste tailings, remove the potassium feldspar in the useless quartz, vein or can be separated from the material, so as to achieve the purpose of separation, compared with the traditional hand sorting process, the overall sorting efficiency is greatly improved. Magnetic Separation     Since iron minerals, black mica, tourmaline, etc. in potassium feldspar are weakly magnetic, they can be removed by strong magnetic separation process and equipment to achieve the purpose of separation. Removal of impurities by flotation     When potassium feldspar contains pyrite, mica, or garnet, tourmaline, hornblende and other forms of ferrite containing minerals, the flotation process is mostly used to remove impurities. The process flow of mineral potassium feldspar beneficiation equipment is as follows.    Crushing: Firstly, the raw ore is crushed by jaw crusher, and then sent by belt conveyor to cone crusher for secondary crushing;   Sorting: After the secondary crushing, the potassium feldspar particles are sent to the circular vibrating screen for sieving and transported to the ore color sorter or artificial intelligence ore sorter for sorting, and the waste stone is thrown away after crushing and dissociation;    Ball Mill: After the waste throwing, the concentrates enter the ball mill for ball milling, and the potassium feldspar powder after ball milling is sorted by spiral classifier;     Magnetic separation: The finely ground potassium feldspar powder enters the magnetic separator for magnetic separation, and the selected iron and mica materials are sorted out by strong magnetism according to the material condition.    Flotation: potassium feldspar through flotation, can be very good to enhance the effect, not only to remove iron, titanium, but also to separate out the quartz and other substances. Among them, according to the potassium feldspar companion does not understand, the use of pharmaceuticals will be different, the main agents are acid flotation, neutral flotation, alkaline flotation method. Dewatering and drying: Potassium feldspar concentrate after magnetic separation or flotation or composite sorting. Dehydration treatment by thickener, then into the dryer for rapid dewatering and drying, and finally the dried potassium feldspar powder is the final sorted potassium feldspar concentrate. Among them, the above process flow 4 and 5 because of the different iron content in potassium feldspar and the different forms of iron ore present in it, sometimes magnetic separation or flotation can be used for sorting, but some potassium feldspar iron ore content is high, and sometimes iron ore exists in potassium feldspar in the form of leaching, this kind of belongs to the difficult ore species, at this time will use the joint beneficiation process for sorting, such as magnetic separation - flotation method, reverse flotation - strong magnetic separation method, etc., at this time can be used Joint beneficiation process, such as magnetic separation - flotation method, reverse flotation - strong magnetic separation method, etc.   From the potassium feldspar beneficiation process, the equipment to be used are jaw crusher, cone crusher, ball mill, vibrating feeder, spiral classifier, ore color separator, artificial intelligence sorter, magnetic separator, flotation machine, dryer, vibrating screen, conveyor, etc. According to the existence of different forms of potassium feldspar, there will be some differences in equipment.    The above is the potassium feldspar sorting process, equipment and process flow, Anhui MINGDER is mainly specialized in ore sorting equipment research and development, production, sales in one of the photoelectric sorting high-tech enterprises, the main products are ore color sorting machine, artificial intelligence sorting machine, mineral sand sorting machine, X-ray intelligent sorting machine, not only use potassium feldspar sorting, in all kinds of metal non-metallic ore are used, covering fluorite, talc, silica The scope of coverage includes fluorite, talc, silica, quartzite, phosphate ore, gold ore, high crystalline silicon, coal and coal gangue, etc.      

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
