Among skarn tungsten deposits, wolframite and scheelite are the most common phenomena, and scheelite also coexists with calcareous gangue minerals such as fluorite, calcite, apatite and garnet. The flotability of scheelite and fluorite gangue minerals is similar, so the flotation separation of scheelite and fluorite is always a technical problem.

Tungsten boride compounds play a very important role in modern industry. They have high melting point, high hardness, wear resistance, high temperature resistance, corrosion resistance and excellent electrical conductivity. They are widely used in high temperature structural materials, refractories, electrode materials, structural materials, wear resistant materials and other fields. With the progress of science and technology, the application fields of B-W series compounds are still in progress. It will be further expanded to show more uses.

Unbonded tungsten carbide ceramics, with better corrosion resistance, have been widely used in corrosive environment as a substitute for traditional cemented carbides. In addition, this kind of ceramics has better high-pressure resistance and high-speed sliding friction than other ceramics when applied to wear materials.

25×100×200mm tungsten copper block is prepared by powder metallurgy method, which has good electrical and thermal conductivity, good high temperature strength and certain plasticity. At very high temperature, such as above 3000 °C, the copper in the alloy is liquefied and evaporated, and a large amount of absorption Heat, reducing the surface temperature of the material.
