Molybdenum processing
The less dense ore rises in the froth to be collected, while the heavier gangue sinks to be discarded. Flotation separates the metallic minerals from the gangue this way and - in the case of copper/ molybdenum ores - separates molybdenite from copper sulfide. The resulting MoS 2 concentrate contains between 85 and 92% MoS 2. Further treatment ...
