The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

The process plant consists of a crushing circuit, grinding circuit, pre-leach thickening and leaching, carbon-in-pulp circuit, carbon elution and regeneration, electrowinning and gold refining, and tailings disposal, with overall gold recovery of 91.2 per cent. Mining will use conventional open-pit blast, load and haul techniques.


(for gold and silver operations), and dump leach materials (for copper leach operations). Leaching involving the use of cyanide is a kind of beneficiation process, usually used with gold, silver, and copper ores, that merits separate attention because of the serious environmental and public safety impacts.
