• Roasting (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/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.
