Molybdenum Processing

Flotation separates the metallic minerals from the gangue this way and – in the case of copper/ molybdenum ores – separates molybdenite from copper sulphide. The resulting MoS 2 concentrate contains between 85% and 92% MoS 2. Further treatment by acid leaching can be used to dissolve impurities like copper and lead if necessary.
