The Mining Process - OceanaGold

The gold is liberated through the reaction between oxygen and sulphur under pressure. Once the reaction starts, fresh slurry is fed into the autoclave and oxidised slurry is discharged to the next stage of the cycle. Stage 3: Leaching and Absorption. The oxidised slurry travels to the carbon leach circuit to dissolve the gold out of the rock.
