The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many lowgrade, hightonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls (Rosas et al., 2012).

The results showed that the SSAG option has a higher installed capital cost when compared with the HPGRbased option, mainly because large AG mill shells are required to compensate for the lack of steel grinding media. However, the SSAG option has lower operating costs when compared the HPGR circuit, mainly due to no grinding media costs.
