SINGLE STAGE SAG/AG MILLING DESIGN ABSTRACT Single stage semi-autogenous / autogenous (S/AG) milling has become a common design for a variety of ore ... Yanacocha 5 Low ball charge, high speed SAG mill (4% ball charge, 90% Nc) ... For these reasons the simulation of a single stage SAG mill for greenfield design using
The Yanacocha gold operation is a single stage SAG mill that was designed to treat 620 t/h at a grind P80 of 75 microns. This was not possible to achieve and grind was saced for tonnage when it was realized that the recovery loss of gold at a P80 of 150 microns was less than 2%.
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 coarse-grinding device, consisting of tumbling drum with .
These mills typically grind ROM ore in a single stage. A large example of such a mill was converted from a single-stage milling application to a semi autogenous ball-mill-crushing circuit, and the application is well described. This refers to high-aspect AG/SAG mills.

The properties of Minera Yanacocha S.R.L. ('Yanacocha') are located 48 kilometres north of the city of Cajamarca, in Peru. Yanacocha began production in 1993 and Newmont holds a 51.35% interest in Yanacocha. Yanacocha has four leach pads, three gold recovery circuits and a new milling circuit (single stage SAG mill,
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.
