For instance, at Lornex Mining, one of the most successful SAG installations, the ball load varies normally from 6-7% by volume of the mill; the ball make-up consists usually of 80% 4-inch diameter balls and 20% 5-inch diameter balls. The ratio of the larger balls is increased when the mill is processing hard ore and decreased with soft ore.
through the inclusion of ore sorting. For an established 40,000T per day plant, a recent evaluation showed that effective sorting could reject sufficient low-grade ore to create the capacity to process an extra 20,000T of copper per year, generating additional profit in the region of $100 million, with no mill expansion (assuming mining
