The Beneficiation flowsheet shown with this study is particularly adapted to the concentration of tungsten ore in small tonnages. Tungsten minerals are generally in the friable class and therefore concentrating processes are hindered by the excess amount of fines produced in the crushing and grinding steps. Special consideration must be given to the stage reduction and concentration …
