The purpose of beneficiation is to separate the mining raw material into useful minerals and useless components.
In practice of mineral processing, some artificial methods are often used to enlarge differences in physical and chemical properties of minerals to help improve the separation efficiency. For example, to change the mineral magnetism by magnetizing roasting, to treat the surface of mineral is treated with acid and salt to selectively change the conductivity of some mineral, to change the natural wettability of minerals under help of various flotation reagents Besides above mentioned methords, the shape, particle size, hardness and color of minerals are also used as some special beneficiation standards.
Gloss is also often the basis for some special mineral processing methods. According to different ore types and requirements for beneficiation products, different beneficiation methods can be adopted in practice. Common mineral processing methods include gravity separation, magnetic separation, electric separation and flotation. The flotation method is the most widely used. Gravity separation method is widely used in the separation of black, non-ferrous, rare metals and coal; The magnetic separation method is mainly used for the separation of ferrous metals and rare metals. It can also be used to remove iron impurities from non-metallic mineral raw materials. It can also be used to purify production water, domestic water and the recovery of magnetite from heavy medium coal preparation; The electric separation method is used for the separation of nonferrous metal ores, rare metal ores, ferrous metal (iron, manganese, chromium) ores, and non-metallic ores (such as coal powder, diamond, graphite, asbestos, kaolin, talc, etc.).
Vibrating screens are widely used in different mining procedures including the preparation of mining rocks and the tailing treatment.
