For instance, at Lornex Mining, one of the most successful SAG installations, the ball load varies normally from 67% by volume of the mill; the ball makeup consists usually of 80% 4inch diameter balls and 20% 5inch diameter balls. The ratio of the larger balls is increased when the mill is processing hard ore and decreased with soft ore.

The first notable application for copper ore came in 1995 at the Cyprus Sierrita copper mine in the USA. However, on account of the extremely abrasive ore, no economical service lifetimes could be achieved for the grinding rolls. The breakthrough came in 2006 at the Cerro Verde copper ore project (Fig. 8) in Peru.
