Grinding Millies Circuit

Initially faced with a blend of primary and oxide ore, the circuit achieved in excess of 320tph until the oxide was depleted, leaving only the much harder primary feed. The 2.0MW semi-autogenous grinding SAG mill and 3.7MW ball mill was assisted by a 150kW pebble crusher, but the power limitation of the SAG mill resulted in a drop in throughput.
