    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 low-grade high-tonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls (Rosas et al. 2012).

    Ball mills are the most common grinding machine employed in the mining industry. Grinding occurs in a single stage or multiple stages. Multiple stages may include a rod mill followed by a ball mill (two stage circuit) or a semi-autogenous grinding (SAG) mill followed by a ball mill (two stage circuit).
