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.

Non ferrous metals refer to all metals except iron and iron base alloys, chromium and manganese. They are also divided into five categories: nonferrous heavy metals, nonferrous light metals, rare metals, precious metals and semi metals. Common nonferrous metals include copper, lead, zinc, aluminum, vanadium, tungsten, lithium, gold, silver, silicon, rare earth, etc. Non ferrous metals are basic materials for national economic development, such as aerospace, automobile, machinery manufacturing, power, communications, construction Most industries such as household appliances are based on nonferrous metal materials.   The distribution of nonferrous metals in China is more in the south than in the north, mainly in the Yangtze River basin. The ore deposits are mostly divided into blocks and belts in spatial distribution. Non ferrous metals are formed in the process of magma cooling, and there are many ways such as gravity, replacement, recrystallization, and sublimation. Most of them occur in fault fracture zones, magmatic rocks, or contact inner and outer zones, fold cores. In terms of mineralization, magmatic rocks are important factors for nonferrous metal mineralization. Nonferrous metal beneficiation is based on the difference of physical and chemical properties of different ores. After crushing and grinding of raw ores, mineral processing technology is used to separate minerals from gangue to remove or reduce harmful impurities. Metal products are produced after smelting. Domestic beneficiation processes mainly include gravity separation, magnetic separation, flotation and electric separation, such as gravity separation of copper, lead, zinc, etc; Magnetic separation of sulfide ores; Flotation of gold, silver, copper, lead, zinc, molybdenum, etc; Separation of scheelite and cassiterite by electric separation, and selection of tantalum niobium ore. The nonferrous metal ores are mostly multi metal symbiosis, and the nonferrous metal grades in ores are generally low. Only when certain reserves and the lowest industrial mining grade are reached, can they have the value of mining and beneficiation. Generally, smelting a ton of nonferrous metals often requires mining hundreds to tens of thousands of tons of ores. In the beneficiation process, most raw ores are directly crushed and grinded without pre throwing waste tailings, resulting in large ore handling capacity, limited production capacity, high energy consumption, high cost, large tailings handling capacity, and large environmental impact of the gravity and magnetic levitation electric separation process, reducing the economic benefits of the mine. However, AI separation can make use of the difference in ore surface characteristics and imaging differences to directly pre dispose the waste tailings, enrich the grinding ore grade, reduce the cost of grinding, beneficiation electricity, reagents, etc. In terms of reducing energy consumption, improving production, increasing benefits, and building smart and green mines in mine beneficiation, AI separation has a wide application space and value for industrial and mining enterprises to enrich and pre dispose the waste. Conventional beneficiation process and flow of non-ferrous metals The vast majority of non-ferrous metals are beneficiated by flotation method, a small part by magnetic separation and gravity separation, and some by chemical or electric separation. The existing mineral processing processes are all based on the physical or chemical characteristics of minerals to dissociate, so as to achieve the purpose of selecting qualified concentrates.   In the flotation method, the raw ore is broken and grinded to fully separate the minerals. With the help of reagents, the useful minerals are attached to the bubbles and the useless minerals are left in the pulp to achieve the purpose of separation. The conventional process of "one roughing, two sweeping and three cleaning" is adopted for flotation separation. Such as chalcopyrite, galena, spodumene, etc. The magnetic separation method uses the magnetic principle of minerals and relies on magnetic fields to distinguish the minerals with strong magnetism, medium magnetism and weak magnetism. For example, chalcopyrite and wolframite are separated from gangue by magnetic separation. By gravity separation, some non-ferrous metals have large density, and the specific gravity of minerals and gangue varies greatly. When mineral particles with different specific gravity move in the same medium, they are loosened by gravity, medium resistance, etc., so as to achieve the goal of mineral separation. Such as wolframite, zircon, cassiterite, etc. The electric separation method mainly uses the different conductivity of minerals and gangue to separate minerals through high voltage electric field. Such as the separation of scheelite and cassiterite, and the separation of tantalum niobium ore and garnet. In chemical method, there are chemical differences between minerals and components. Solid metal minerals are dissolved into liquid through acid, ammonia and other leachants, such as copper ore in malachite. Copper sulfate solution is obtained by soaking in dilute sulfuric acid. Enriched copper can be obtained by replacing copper ions with iron ions. In a word, most nonferrous metals have low grade in nature as a whole. Only through crushing grinding floating magnetic gravity electrochemical method can minerals be enriched. However, the tailings waste a lot of electricity and reagents due to the above processes, resulting in high selection costs. Artificial intelligence and X-ray intelligent sorting system Mingde artificial intelligent sorter and X-ray intelligent sorter are two series of products developed with great concentration through technical accumulation and advantages, combined with the difficult problems of separation and beneficiation in industrial and mining enterprises. It is applicable to most nonferrous metals, ferrous metals, nonmetals, and others such as coal gangue and solid wastes. It can discard tailings, enrich ore grade, reduce grinding and dressing costs, and increase economic benefits of industrial and mining enterprises.   In the flotation method, the raw ore is broken and grinded to fully separate the minerals.
