Ø Effect of SAG Mill Feed Size Distribution and Ore

2021-1-12  Ø Recycle crusher availability was lower than that of the SAG mill. Ø SAG mill availability was lower than expected in the first year due to issues with the gearless drive and trommel panel failures. Figure 1 shows the ramp up of the Cadia Hill SAG mill by quarter. Throughput and availability are presented compared to the target or design basis.
