Magnetic Separation of Fine Mineral Sulphides

The separation of fine sulfides becomes increasingly difficult at fine particle sizes. Potential fine size separation methods are froth flotation and magnetic separation. The mineral sulfides, with the exception of pyrrhotite, are either weakly paramagnetic (e.g. chalcopyrite) or diamagnetic (e.g. molybdenite). Those which are paramagnetic can only be separated using high-gradient magnetic ...

Roasting (metallurgy) - Wikipedia

Roasting is a process of heating a sulfide ore to a high temperature in the presence of air. It is a step in the processing of certain ores.More specifically, roasting is often a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth ...
