Molybdenum is frequently associated with tungsten in mineral deposits, and their chemical properties are quite similar. Therefore, for many years, removal of impurity molybdenum from tungsten has been a worldwide technical problem. In this work, a separation process was investigated with the use of copper-bearing materials as the scavenging agents.
The copper-molybdenum separation electric potential flotation process comprises the steps of raw ore crushing, ore grinding, mixed flotation and separation flotation. In the separation flotation step, the ph value of pulp is kept at 10-11, and rougher flotation pulp electric potential is controlled to -510 mv to -530 mv; and then 180 ml/min of ...
