Newcrest's Cadia Hill mine, the second-largest open pit gold-copper mine in Australia, produces approximately 300,000 ounces of gold annually. But its low-grade ore requires costly bulk mining and treatment techniques. Newcrest applies the Six Sigma quality improvement methodology and Minitab® Statistical Software to keep the Cadia Hill ...

The Ridgeway Concentrator at Newcrest Cadia was commissioned in 2002 as an ABC circuit to treat the ore from the Ridgeway sublevel cave (SLC) at around 5 MTPA. Consisting of a single pinion 32' autonomous grinding (AG) mill and a single pinion 7 MW ball mill, it was a much smaller plant than the adjacent Cadia Hill Concentrator. Subsequent …
