Abstract This study aims to indie which measurements are required in order to estimate the volume of rocks and balls in a semiautogenous grinding mill as two separate states. The nonlinear observer model used here includes the following process states: water, solids, rocks, and balls in the mill, where solids are all ore small enough to discharge through the enddischarge grate, and rocks ...

The addition of the ball mill in 2018 allowed the mill feed tonnage to be maintained at Mtpa on the harder sulphide ore types, while also reducing the hydrocyclone overflow P80 size. Hydrocyclone overflow from the grinding circuit is screened to remove trash (, wood chips, plastic, etc.) and is then pumped to the new 28 m diameter Outotec preleach thickener.
