ABSTRACT The run of mine ore from Aghdarreh gold mine must be comminuted to achieve the desired degree of liberation of gold particles. Currently, comminution circuits include a singlestage crushing using a jaw crusher and a singlestage grinding using a SemiAutogenous Grinding (SAG) mill in closed circuit with a hydrocyclone package.

Early SAG mills had a diameter of about 32', later increasing to 34, 36, 38 and 40'. At the same time the mill volume also increased. Typically a SAG mill has a much larger diameter compared to its length. Yet the SAG mill of Newmont's Yanacocha mine in Peru is a single stage mill (no ball mill after the SAG mill.

Firstly, there was a serious flaw in the power configuration 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.
