Autoclave and Pressure Oxidation Mining and Minerals

Autoclave and Pressure Oxidation Pressure oxidation was developed for processing refractory ores where gold is occluded in the sulfide minerals, typically pyrite or arsenopyrite. Oxidation of the sulfides at elevated temperatures and pressures liberates the gold, allowing it to be economically recovered by conventional circuits.
