tungsten mining beneficiation

Mining & Beneficiation - International Tungsten Industry Association

Tungsten Mining & Beneficiation. Tungsten is usually mined underground. Scheelite and/or wolframite are frequently located in narrow veins which are slightly inclined and often widen with the depth. Open pit mines exist but are rare. Tungsten mines are relatively small and rarely produce more than 2000t of ore per day.
