Apr 01, 2013· 1. Introduction. The Run-of-mine composition strongly affects autogenous mill operation. However, the effects of a varying ratio of hard and soft components in mill performance are not described by the current generation of AG/SAG models (Stange, 1996).For example, current JKSimMet models (Napier-Munn et al., 1996) assume a uniform feed, and describe it using a single set of average ore
