Roasting (metallurgy)

Roasting is a process of heating of sulphide 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 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 flotation
