Crushed ore will then be transported to the primary and secondary grinding sections via underground feeders. At the grinding section, the ore will be processed into slurry using a 28MW gearless drive semiautogenous (SAG mill) and two gearless drive ball mills. The slurry will then be delivered to the flotation section of the concentrator.

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.
