Tungsten and molybdenum are accompanying elements in tungsten mine. However, in tungsten concentrate beneficiation, its hard to separate them because they are similar element, both belong to VIB clan in periodic table of elements. It results in over 41% of tungsten resource are wasted due to its high molybdenum content. This greatly shortens service life of tungsten resource in China.

After artificial beneficiation, tungsten concentrate will enter gravity separation process. Crush means crushing coarse tungsten concentrate in to relative specification and enters next step of tungsten concentrate gravity separation. It needs to be completed by crusher.

Phosphotungstic heteropoly acid is a kind of heteropoly tungstate, is also called keggin type phosphotungstic or dodecaphosphotungstic acid. It is a kind of solid strong acid, can be used as catalyst in organic catalytic reaction. It has excellent catalytic property.

After artificial beneficiation, tungsten concentrate will enter gravity separation. In grinding and tungsten slime recovery process need fine grinding, the equipment is ball mill.

After artificial beneficiation, tungsten concentrate will enter gravity separation process. Grinding process is coarse grinding. Rod mill is to grind tungsten concentrate for the jigging separation in next step. It is not simple grinding. 

Centrifugal separator, also known as centrifugal chute, it is the use of mineral particle size and density differences in the high-intensity centrifugal force field, can achieve separation of useful minerals and gangue minerals.

Micro-emulsion method is effective way for producing super micron grain in recent years. The two medium is separated by surface active agent and form into emulsion. In this circumstance, tungsten element will react and form into solid phase grain, limit nano grain to grow up and accumulate, so the formed nano grain is covered by a layer of surface active agent, has a certain accumulating structure.

Tungstic acid is an important chemical product of tungsten, it has wide application, chemical formula is mWO3·nH2O. Tungstic acid is poly chemical compound of combination with WO3 and water by different ratio, the common seen tungstic acid includes yellow tungstic acid, white tungstic acid and metatungstate.

Calcium tungstate is also called artificial scheelite, chemical formula is CaWO4, they have same composition but different function. Tungsten scheelite is original mineral without processing, calcium tungstate is chemical products of tungstate.

Electric separation utilizes different conductivity of mine and vein mineral grain, can process electric classification and separation in high voltage electric field. It is effective method to separate tungsten and tin in tungsten scheelite. But it is also used in tungsten concentrate gravity separation.
