The plant consists of a two-stage crushing circuit, a standard SAG and Ball mill (SABC) grinding circuit, a gravity circuit, a Leach/Carbon in Pulp (CIP) train, a pressure Zadra elution circuit, a tailings recovery (TR) circuit and a thickened tailings storage facility (TSF). Currently, the overall metallurgical recovery averages around 92.6%.

Dec 23, 2019· The stripped carbon is regenerated in an oil fired kiln and then reused. After leaching, the barren slurry after removal of the gold is pumped to the tailings dam 3 kilometres southeast of the process plant for final disposal. The gold is recovered from the solution by electroplating onto stainless steel wool cathodes.

The residual gold content found in the flotation tailings is recovered through a carbon-in-leach circuit. The processing equipment used at the mine includes two 60X113 primary crushers, five MP 1000 secondary crushers, four high-pressure grinding rolls and four ball mills.
