gold processing Mining and concentrating Britannica
Such ores are referred to as refractory, and they frequently contain the sulfide minerals pyrite, pyrrhotite, or arsenopyrite. Gold can be freed from these ores or concentrates by treating them with various oxidizing processes. The most common method is to roast gold-bearing minerals at temperatures of 450° to 750° C (840° to 1,380° F) to
