low aspect SAG mill operated with a very high ball load in closed circuit, the power response is generic. Fig. 3 illustrates the expected throughput response of a generic SAG mill based on simulations conducted by Morrell (Powell et al., 2001) for a range of ore hardness, AG/SAG operation, open circuit (oc) and closed circuit (cc) operation.
