Autogenous and Semi-autogenous Grinding Circuits
open-circuit the primary mill to better balance the grinding load with the secondary mill. The coarse transfer size to the ball mill makes this circuit unsuitable for most fine-grinding applications such as gold ores with 100 µm P 80 targets. It is mostly employed in huge porphyry copper mines with >100 kt/d throughput with coarse P 80
