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.

The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached. First the copper ore from a open pit mine is blasted, loaded and transported to the primary crushers. Then the ore is crushed and screened, with the fine sulfide ore (~-0.5 mm) going to froth flotation cells for recovery of copper.

Learn About Copper The Balance

Mar 26, 2018 · Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0 percent copper. The refining techniques employed by copper producers depend on the ore type, as well as other economic and environmental factors. Currently, about 80 percent of global copper production is extracted from sulfide sources.
