Roasting (metallurgy)

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 ...
