Tungsten waste recycling utilization, it is well known that tungsten is a kind of rare metals, rare metals are important strategic resources, and tungsten has very important application. It is an important part of contemporary high-tech new materials, a series of electronic opti- cal materials, special alloys, new functional materials and organic metal compounds, etc. All needs to use the unique properties of tungsten. Naturally, tungsten waste this kind of secondary resources, its recycling has a very high economic value.
Tungsten waste mainly include two categories:
- one kind is the tungsten and tungsten alloy material processing scrap, such as sintering material rod end (head), tungsten carbide workshop ground of garbage, grinding carbide slag and metal oxide coating and cutting pieces, etc.
- Another kind is wear, wear out or abandoned containing tungsten materials, such as waste tungsten carbide cutting tools and spent catalyst.
