tungsten mining processing

The material cycle starts with the extraction of tungsten ores from natural stocks in mineral deposits. Tungsten ores are crushed, grounded, and concentrated by a combination of gravity separation, flotation, and/or magnetic processing steps (Stafford, 1988) to produce the concentrate containing 50%–70% tungsten trioxide (WO 3).
