Grinding Circuit - an overview ScienceDirect Topics
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 .
