tungsten processing, preparation of the ore for use in various products. Tungsten exhibits a body-centred cubic (bcc) crystal lattice. It has the highest melting point of all metals, 3,410° C (6,170° F), and it has high conductivity for electricity. Owing to this unique combination of properties, it is used extensively as filaments for incandescent lamps, as electric contacts, and as ...

In recent years, relevant domestic institutions have trial-produced tungsten crucibles. As a result, the rare earth products after smelting contain tungsten only 1000 x 10-6, which greatly meets customer requirements. And the service life of the crucible is up to 400-500 times. It can be continuously used for 5-6 months, smelting 12 times per day.

The process itself can be done via chemical or physical treatment. Examples of direct recycling processes include: The zinc process: This process involves exposing tungsten carbide scrap to molten zinc and zinc vapour in the presence of argon or nitrogen at furnace temperatures of 800 °C to 1050 °C for a prolonged duration of time. The liquid zinc reacts with the binding metal (copper, nickel or iron), which bloats the scrap as the binder volume increases.
