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. Grinding circuit data had to be reconciled due to inability to calculate the circulating load of these circuits with good accuracy. Complex circuit analysis with data redundancy in mineral processing historically requires a wide sampling campaign and the use of matrix calculation for each mineral component present in each considered flow.
