process beneficiation of tungsten ores

Scheelite (CaWO 4) and wolframite ((Fe, Mn)WO 4) are the only tungsten minerals mined commercially and are mainly found in five types of deposits: skarn, vein/stockwork, porphyry, disseminated and stratabound.Gravity concentration and flotation are the beneficiation techniques most commonly applied to scheelite ore, and gravity and/or magnetic separation for wolframite ore
