Tungsten processing flow. The mined tungsten ore is initially crushed by jaw crusher, and after being crushed to reasonable fineness, it is uniformly fed into a ball mill by a hoist and a feeder, and the ore is crushed and ground by a ball mill. After the ball mill grinding fine ore into the next process classification, spiral classifier by ...

Tungsten is one of the most important refractory metals. It is used in the production of numerous end-use items such as incandescent lamps and hard materials. From its ore concentrates and oxidized scrap, tungsten is processed via a hydrometallurgical route. In the last 100 years there has been a significant change in its processing. This paper reviews the methods employed in the ...
