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.READ MORE
The conventional process for production of ferromolybdenum starts with molysulphide concentrate anlaysing over 55% molybdenum . Molysulphide concentrate is roasted to molybdic oxide which is either used as such or is further purified. The purification treatment involves a combination of oxide distillation followed by hydrometallurgical processing .READ MORE
