2019.2.16 Low-grade molybdenum concentrate is a typical resource to extract molybdenum, but it has long been used inefficiently due to its high contents of impurities such as Ca, Fe, Pb, and Cu. In this study, the deep purification of low-grade molybdenite concentrates have been investigated via both theory and experiments.

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 by acid leaching dissolves impurities like copper and lead, if necessary.
