Ridgeway Gold and Copper Mine, New South Wales Mining

A two-stage grinding process forms a part of the comminution circuit. The grinding circuit comprises a 6.5MW SAG mill and 6.5MW ball mill. Using similar processes to the adjacent Cadia Hill concentrator, gold and copper are recovered in a conventional floatation circuit to produce a copper concentrate containing elevated gold levels.

Siemens modernises SAG mill gearless drive in Cadia Valley

27/03/2012· At the Cadia Valley Operations, Newcrest operates two underground mines and one open pit mine. Ore is processed to a heavily auriferous copper concentrate in a crushing, grinding and flotation circuit. This two-stage grinding circuit consists of a 40 ft SAG mill with a 20 MW Siemens gearless drive and two parallel 10 MW gear driven ball mills.
