Abstract
A system and method for recovering gold using pressure oxidation is disclosed. In one embodiment, a feed slurry is introduced into multiple compartments or stages of a multi-stage autoclave. In another embodiment, an agitator pump is disposed in each compartment or stage of an autoclave to draw the feed slurry and oxygen into a pump cavity for intimate mixing. Preferably these embodiments are used in combination, and each is believed to contribute to enhanced utilization of the oxygen within the autoclave.
