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 results show that grinding time is a significant factor affecting the particle size composition. The suitable grinding concentration of Tongkeng ore and Gaofeng ore is 70% and 75%, respectively. The effect of mill filling ratio on Gaofeng ore is not obvious. The rotational rate has little effect on the grinding technical efficiency.

The ore and grinding media are rotated in the mill, which causes the ore to break down into smaller particles. The resulting slurry is then fed into flotation cells for further processing. The grinding process for copper ore in Australia can be energyintensive and costly, particularly if large amounts of ore need to be processed.
