autoclave for gold mining

Autoclave Circuit Gold Mineral Processing Metallurgy

Autoclave Circuit Gold Slurry from the grinding circuit, at approximately 35% solids and 8085% passing 135 mm is pumped to three thickeners. Thickener underflow, at approximately 54% w/w solids, is pumped to a train of four acidulation tanks.


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.
