Each mill measures about 12 metres in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart. From the AG mills, the ore travels to the primary magnetic separators where the iron is drawn away from the waste material before it's screened and fed into the ball mills.

SAG mill. SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.

For example the ore entering a semi-autogenous grinding (SAG) mill will typically have material ranging in size from fine sand to rocks up to 150mm. The harder rocks will be worn away slowly and these pebbles play a significant roll in the mill. The balls usually constitute about a third of the volume of the charge in a SAG mill.
