Crushing and milling account for just over 50% of copper mine site energy consumption 3 making them a primary target for cost reduction. The goal is to grind the ore just enough for optimum copper mineral liberation in the froth flotation plant circuit. Undergrinding reduces recovery; overgrinding reduces throughput and wastes energy.

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.
