How To Recover Gold From Gold Ore Concentrates

Gold Ore Processing sciencedirect. Abstract. Oxidation releases encapsulated gold grains from the sulfides and makes the oxidation residue of the ore or concentrate amenable for gold recovery by cyanidation in a subsequent leaching step. Pressure oxidation of gold ores is therefore a pretreatment leaching step to enhance gold recovery.
