Tungsten Processing International Tungsten Industry

Contaminated cemented carbide scrap, turnings, grindings and powder scrap are oxidized and chemically processed to APT in a way similar to that used for the processing of tungsten ores. If present, cobalt, tantalum and niobium are recovered in separate processing lines. Other tungsten containing scrap and residues might require a modified process.

Why Tungsten Recycling is as Important as Tungsten

2019-1-27 Tungsten carbide is one of the strongest materials known and is widely used in machine cutting tools. However, the amount of tungsten available worldwide is limited and finite. This is why tungsten recycling is just as important as tungsten processing from the point of view of the industries that rely on the material.
