The circuit consists of a singlestage, low aspect ratio (diameter:length = ) mill, typical of the majority of SAG mills in the South African gold mining industry. These are locally known as runofmine, RoM, mills. The mill is operated at 90% of critical speed and with a volumetric load of 40%.

of the SAG mill and ball mill (both rated at 6000 kW with a single pinion drive). The capacity of the SAG mill was not fully utilized, as the actual operating power draw was only 3358 kW. This meant it was only operating at 56% of its maximum power, providing large room for improvement. The load on the ball mill was on the high side, with an actual operating power draw of 5300 kW, meaning it was operating at .

The thesis has provided improvements to the previous AG/SAG mill discharge understanding in terms of discharge rates and grate classification in relation to mill load and operating parameters.

The SAG mill is fed from a single stage crushing circuit/ etc and operates in closed circuit with a set of cyclones. The SAG mill shall be a grate discharge mill. Circuit diagram is enclosed.
