In the traditional recovery and treatment of waste tungsten powder, the powder waste tungsten powder is first oxidized into tungsten oxide, and then tungsten oxide is dissolved by alkali to form tungstate. In this way, not only the process is complex, but also the efficiency is very low. The oxidation rate of waste tungsten powder is usually less than 50%. Unoxidized tungsten powder needs to be recycled by other methods again.

Tungsten is one of the metals with the highest melting point and the most common arc electrode material. Tungsten electrode material is mainly used in tungsten argon arc welding. It is generally used as cathode part in the process of argon arc welding. It is almost suitable for welding all metal materials.

Tungsten alloy blank refers to tungsten alloy semi-finished products of various shapes. The tungsten alloy blank is further processed to prepare various tungsten alloy products. The main categories include: tungsten alloy billet, tungsten alloy bar, bar, cube, brick, block and tungsten alloy plate, etc. The common tungsten alloy blanks are mainly castings, forgings, profiles, welding parts and so on.

With the rapid development of economy, the demand for tungsten metal materials is increasing. Almost all the metal elements constituting cemented carbide materials are rare elements. It is increasingly urgent to make comprehensive use of various tungsten resources. Over the years, the industry has done a lot of work on the comprehensive utilization and regeneration of tungsten resources. At present, the recovery and utilization of waste tungsten accounts for 20% of China's tungsten consumption. The regeneration and utilization of tungsten resources plays an important role in the national economy.
