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%.

4 The SAG mill model in the JKSimMet software has not been shown to accurately reproduce the performance of a single stage mill for greenfield design. A review of most modern power models shows that the prediction of specific energy is influenced by the high energy breakage characteristics of the ore (DWi, t 10, SPI etc.) and the low energy (BWi).

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…

Obviously, the SAG mill is consuming more and the ball mill less power than was predicted by the empirical method, but the overall total is 99.5% of the predicted total. Examples. The Hemlo gold project of Teck-Corona (1000 mtpd) provides an example of mill sizing using the empirical calculation method alone.
