beneficiation of tungsten ores

Mining & Beneficiation - International Tungsten Industry AssociationTungsten 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.

For the exploitation of a low grade tungsten deposit of Tapaskonda, A.P., India containing 0.1-0.16% WO3, preconcentrate with 13.06% WO3 was produced by physical beneficiation. This concentrate containing ferberite along with small amount of wolframite minerals was treated following two routes viz.

Beneficiation of tungsten ores in India: A review | SpringerLink

The strategy needed for the techno-economic feasibility of beneficiation of low grade tungsten ores are (i) effective pre-concentration at as coarse a size as possible, (ii) emphasis on higher recovery rather than on high grade of the concentrate, (iii) a two-product approach, one of high grade feasible by physical beneficiation.
