Circuit perfomance for a sag mill

Abstract: The paper proposes a novel performance audit report for a SAG Mill Circuit. The audit report is demon strated on a validated run -of-mine ore grinding circuit model, which the authors have captured in a simulator, using Simulink. The elements of the report combine established statistics and views with
