Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach.
Commissioning of the Cadia Hill SAG mill Circuit followed a project Research and Development exercise in July 1998. The SAG mill quickly reached 90% of the design rate but it became evident that the mill would not meet design throughput at the design operating conditions of ball and rock charge, mill speed and power draw.
