gold processing
Gold can be freed from these ores or concentrates by treating them with various oxidizing processes. The most common method is to roast goldbearing minerals at temperatures of 450° to 750° C (840° to 1,380° F) to destroy the interfering sulfides. Oxidation can also be accomplished by the use of highpressure reactors called autoclaves, in ...
