AG/SAG Mill Circuit Grinding Energy Requirement - How

obtained for each ore type. The AG/SAG operating work indices show their usual elevated levels compared to those from the ball mill circuit. This has often resulted in conclusions concerning lower energy efficiencies of AG/SAG mill circuits compared to ball mills. The correlation between the AG/SAG and ball mill circuit data is also very poor.
