The process selection and design aspects to treat primary ore in a new carbon-in-pulp (C.I.P.) plant while utilizing, where possible, existing equipment and infra- structure are discussed. The existing crushing plant, water supply, reagents, laboratory and infrastructure facilities from the heap leach have been upgraded and expanded to meet the C.I.P._x000D_
plant requirements. The new power supply is from the North Queensland grid system. A series of metallurgical tests was carried out and a review of the data showed that the primary ore was amenable to conventional cyanide leaching. Following feasibility studies, a new process plant which included grinding mills, leaching, and adsorption tanks, thickener, desorption and gold roam facilities was constructed.
