The Mining Process OceanaGold

Gold at Macraes is known as refractory ore, which means it is ultrafine 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 threestage processing cycle to ensure the gold is
