Scheelite is a kind of mineral resource which is not easy to be mined. It often coexists with calcium gangue, has low geological grade and is relatively difficult to beneficiate. In order to obtain qualified scheelite concentrate in industry, flotation technology is widely used in the process of selecting scheelite. The most traditional method is heating flotation.

Ø9x200mm tungsten copper rod with diameter of Ø9mm and length of 200mm, the general diameter tolerance is ±0.5mm and length tolerance is 0 to +5mm. With excellent electrical and thermal conductivity, uniform microstructure, high temperature resistance, high strength, arc erosion resistance, high density; moderate conductivity and thermal conductivity.

Ø8x200mm tungsten copper rod with diameter of Ø8mm and length of 200mm, the general diameter tolerance is ±0.5mm and length tolerance is 0 to +5mm. As a contact material, it has very good machinability and thermal shock resistance. Due to arcing during contact and breaking, the contact material will rise by several thousand degrees Celsius in a fraction of a second.

Cobalt tungsten carbide powder has high hardness and excellent wear resistance, and is widely used as cutting tools, wear-resistant tools, impact-resistant tools and metal casting materials. Moreover, when WC powder particles are finer, it has higher hardness and wear resistance.

Selective Catalytic Reduction (SCR) flue gas denitrification technology has the advantages of high denitrification efficiency, good selectivity, maturity and reliability. It is widely used in thermal power plants and is the mainstream of denitrification in coal-fired units. The main active components of catalysts used in SCR denitrification are titanium dioxide, V₂O^-, WO₃ and MoO₃, which account for more than 90% of the catalyst composition.
