Reselection method

The gravity separation method is used to separate minerals according to the difference of mineral relative density (usually called specific gravity). Mineral particles with different densities are subject to hydrodynamic and various mechanical forces in the moving medium (water, air and heavy liquid), resulting in suitable loose layering and separation conditions, so that mineral particles with different densities can be separated.

Flotation method

According to the difference of physical and chemical properties of mineral surface, the flotation method is to selectively attach useful minerals to bubbles after flotation agent treatment, so as to achieve the purpose of separation.

The beneficiation of non-ferrous metal ores, such as copper, lead, zinc, sulfur, molybdenum and other ores, is mainly treated by flotation; Some ferrous metals, rare metals and some non-metallic ores, such as graphite ore and apatite, are also separated by flotation.

Magnetic separation

The magnetic separation method is based on the different magnetic properties of minerals. Different minerals are subject to different forces in the magnetic field of the magnetic separator, so that they can be separated. It is mainly used to separate ferrous metal ores (iron, manganese, chromium); It is also used for the separation of nonferrous and rare metal ores.

Electric separation

The electric separation method is based on the difference of mineral conductivity. When the mineral passes through the high-voltage electric field of the electric separator, the electrostatic force acting on the mineral is different due to the different conductivity of the mineral, so the mineral can be separated. The electric separation method is used for the separation of rare metals, nonferrous metals and non-metallic ores. Mainly used for separation and concentration of mixed coarse concentrate; For example, the separation of scheelite and cassiterite; Selection of zircon, tantalum niobium ore, etc.
