2022.3.30 As there are no SAG mills and no ball mills in the HPGR-HPGR circuit there are additional savings in CO 2 from the fact that steel ball consumption is zero. A further 15 megatonnes of CO 2 is therefore estimated to be potentially saved, giving a total saving of 34.5 megatonnes of CO 2 or 43.2% compared to a AG/SAG-Ball mill circuits.

Slurry pooling, excessive accumulation of slurry in the mill, and the associated loss of throughput and grind, are well recognised on lowaspect, single-stage SAG mills. However, it is becoming apparent that a wide range of the high-aspect mills also suffer from pooling issues. This is associated with the high throughput of mills treating less competent ores,
