Beneficiation Process of Tungsten Ore-1

Tungsten ores and concentrates are converted into the following intermediate products: APT, tungsten acid, sodium tungstate, tungsten metal powder, ferrotungsten, and tungsten carbide powder. Most of the APT is reduced to tungsten metal powder, which then may be processed into tungsten carbide powder or ferrotungsten.” End uses of tungsten include metal working, mining, and construction machinery and equipment, 74%; electrical and electronic machinery and equipment and transportation, 10%; lamps and lighting, 9%; chemicals, 4%; and other, 3%.

Tungsten Ore Process

Tungsten ore is found in three forms: WS2 (rare), CaW04 (Sweden) and (FeMn)W04. We need the Mn just as much as the W, so don’t waste it. The first process is gleaned from the 1958 “Rare Metals Handbook”. First, the ore must be reduced to face powder size. We today would crush and grind, but that equipment and the alloys to build it, just will not be available for a long time.
