Tungsten Ore Recycling is an important factor in the world’s tungsten ore supply. It is estimated that today some 30% is recycled, and the tungsten ore processing industry is able to treat almost every kind of tungsten-containing scrap and waste to recover tungsten ore and, if present, other valuable constituents.
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 ore containing scrap and residues might require a modified process.
