Process for recovering gold from refractory sulfidic ores

A process for recovering gold from a refractory sulfidic ore which has been suspended in an aqueous slurry and oxidized using nitric acid so that substantially all of the gold in the ore is made available for recovery and at least a portion of the sulfidic components present during the oxidation are oxidized to elemental sulfur comprises bubbling air as a discontinuous phase

The Mining Process

Gold at Macraes is known as refractory ore which means it is ultra fine and resistant to the typical cyanide leach process typical of most gold processing plants This refractory nature of the ore led to inefficiencies recovering the gold from ore in the past The ore now goes through a three stage processing cycle to ensure the gold is
