Roasting is a process of heating of sulfide ore to a high temperature in presence of air It is a step of the processing of certain ores More specifically, roasting is a metallurgical process involving gassolid reactions at elevated temperatures with the goal of purifying the metal components Often before roasting, the ore has already been partially purified, e g by froth flotation
