Tungsten Ores and Concentrates - processing of tungsten ore
Scrap (Secondary Tungsten Sources) Tungsten scrap due to its high tungsten content in comparison to ore is a very valuable raw material. 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.Tungsten is extracted from ore through a series of chemical reactions. The exact process varies by manufacturer and ore composition, but ores are crushed then roasted and/or sent through a variety of chemical reactions, precipitations, and washings to obtain ammonium paratungstate (APT).
