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.

AG/SAG mills for a given feed size distribution and feed rate (Morrell and Morrison, 1996). Hence when using JKSimMet in a design situation, the dimensions of the AG/SAG mill are adjusted until the load in the mill reaches 25 % by volume when fed at the required feed rate. The model predicts the

20 to 30 TPH for gold ore SAG Ball Mill duty; 25 to 40 t/h for copper porphyry SAG Ball Mill duty; In Single Stage SAG duty, the approximate capacity reduces to only 8 to 13 TPH for gold ore duty. The autogenous mill itself is a coarsegrinding device, consisting of tumbling drum with .
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.
The properties of Minera Yanacocha ('Yanacocha') are located 48 kilometres north of the city of Cajamarca, in Peru. Yanacocha began production in 1993 and Newmont holds a % interest in Yanacocha. Yanacocha has four leach pads, three gold recovery circuits and a new milling circuit (single stage 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.

The DFS confirmed the robust nature of the Project with an initial operating LOM of over 7 years, producing approximately 106,000 ounces of gold per annum on average from a single open pit, with ore processed through a plant utilising a single stage crushing circuit and SAG mill, sulphide flotation, regrind mill followed by conventional cyanide ...
These mills typically grind ROM ore in a single stage. A large example of such a mill was converted from a singlestage milling application to a semiautogenousballmillcrushing (SABC) circuit, and the application is well described (Mainza et al., 2012). This section refers to highaspect AG/SAG mills.
