ore concentrate grinding

Molybdenum Processing

The less dense ore rises in the froth to be collected, while the 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 sulphide. The resulting MoS 2 concentrate contains between 85% and 92% MoS 2. Further treatment by ...

Ore Dressing - Sympatec

Ore Dressing. The primary and secondary grinding takes place in autogenous (AG) or semi-autogenous (SAG) mills and in ball or rod mills. If the raw material is sufficiently finely distributed, it is classified in wet-chemical flotation cells according to reusable material and waste rock (residual mineral). The material substrate obtained is called concentrate.
