Molybdenite (MoS2) concentrates are produced by differential flotation from bulk copper-molybdenum concentrates. However, complete separation of molybdenum by flotation is very difficult, thus, molybdenum concentrates produced by this route requires a further step of chemical purification in order to reduce the copper content to a suitable level for marketing. Refractory chalcopyrite (CuFeS2) is the major copper mineral impurity in these concentrates This paper is concerned with a novel process of chemical purification of molybdenite concentrates containing chalcopyrite as the main copper impurity. The process involves a sulfidation of the molybdenum concentrate with 82(g) at 380 °C followed by a leaching stage.
