Roasting (metallurgy) Wikipedia

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 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.

Gold Ore Roasting Plant Mineral Processing & Metallurgy

Why Roast? Some gold ore at the Roaster is double refractory. First, the gold is locked in sulfide mineral particles that must be oxidized to expose the gold for cyanide leaching (Autoclaves do this function effectively). Second, the ore also contains preg- robbing carbon that will collect solubilized gold in the leaching circuit if it is not
