Concentrates International Tungsten Industry Association ...

Concentrates. Marketable ore concentrates of scheelite and wolframite (hübnerite, ferberite) contain typically 65 – 70 % WO 3.Off-grade concentrates having lower WO 3 concentrations are seldom on the market and if so, only for a lower price. In fully integrated companies lower grades (6-40% WO 3) are often preferred, because upgrading to high concentrations is mostly combined with a lower ...
