In the existing market, the price of high-performance ultra-fine tungsten carbide powder is about one to two times that of ordinary micron-sized tungsten carbide powder, and the production costs of both are basically the same. Therefore, the production of ultra-fine tungsten carbide powder is a effective way for tungsten upgrading.

Tungsten electrode made of tungsten is widely used for welding because of its high melting point, corrosion resistance, high density, good heat conduction and conductivity. It is especially suitable for TIG welding and other electrode materials similar to this kind of work.

At present, MIM has become the most promising near-net-size forming technology in the international powder metallurgy field. It is known as one of the “hottest metal parts forming technologies in the world”. The metal powder injection molding technology (MIM) is a plastic molding process. 

Tungsten has high melting point, high hardness, good high temperature strength, heat conduction, electrical conductivity, low coefficient of thermal expansion, low sputtering with plasma, no chemical reaction with H, low retention of H+, etc. It is a very important high-temperature structural material and functional material. It is widely used as material for plasma and divertor parts in nuclear fusion.

In view of the various reasons for the loss of fine grain scheelite in ore dressing, from different angles, the beneficiator put forward some selection methods for fine minerals, such as flotation column flotation, vacuum or decompression flotation, selective flocculation flotation, carrier flotation, two liquid flotation, electrochemical flotation, shear flocculation and so on, but it should be practical in practice. The effect is not obvious in the use of the process.

China is recognized as a fluorite resource country, producer, and exporter in the world. The reserves, extraction volume and export volume rank first in the world. Fluorite is the most important mineral in fluoride. It has unique physical and chemical properties, and has a wide range of uses. It plays a decisive role in industrial development. However, China's single-type fluorite deposits have small reserves, and the rich tungsten ore with a CaF₂ grade of more than 65% is less than 23% of China's fluorite reserves. Most of the fluorite resources are associated minerals and are mainly associated with scheelite.

The addition of a certain amount of rare earth elements to tungsten can change the performance of the tungsten wire and at the same time improve the tungsten processing performance. Tungsten alloy wire and products produced by using these characteristics are mainly used for electronic tube hot wire, argon arc welding electrode, and pulse tube heating wire.

Tungsten and molybdenum are similar elements, and their properties are very similar. Therefore, separation of tungsten and molybdenum has been an important research direction in tungsten metallurgy.
