Evolution Mining is a leading, growth-focussed Australian gold miner since 2011. Their operations are in Queensland, Western Australia, and New South Wales.
Cowal Gold Operations (CGO) is located on the traditional lands of the Wiradjuri People, approximately 350Km west of Sydney. The mine is licensed to 7.5M t/y and treats 7.3M t/y with approximately 5-8% of the feed reporting to sulphide concentrates on regrinding and subsequent cyanide leach. The plant includes a primary crushing circuit, SABC (SAG and balls mills, with pebble crusher), flotation cells and a CIL circuit.
CPC Project Design provided Feasibility Studies services to GCO. The scope of work included:
- Installation of a new leach circuit to treat flotation tails and detoxification of this stream before pumping to the tails storage facility
- Installation of new carbon handling and electrowinning facilities to treat the gold recovered from flotation tails leach circuit
- Installation of new reagent mixing and distribution systems needed for the operation of the leach circuit, detoxification facilities and carbon handling facilities
