Yanacocha Gold Single Stage SAG Mill Design, Operation

The Gold Mill was commissioned in March 2008 with a 32? x 32? EGL, 16.5MW single stage SAG mill, to process 5 million tonnes per annum high grade oxide Au/Ag ore. Operational control, feed size distribution, grinding media, mill liner, grate and pulp lifter optimisation have allowed the mill to operate 15-30% above design throughput rates, but with a product P80 coarser than design.

01-01-2016· The largest volume mill in the world was constructed for Tarkwa, Ghana, in 2004. The mill is 8.23 m diameter by 12.19 m effective grinding length (EGL) or inside liner length. The mill is operated in a single-stage grinding circuit. Most AG and SAG mills have slotted steel and rubber liners and are fitted with lifter bars.

Selection of Comminution Circuits for Improved Efficiency

• Single stage crush/single stage SAG mills and two stage crush/ball mill circuits are typically selected for low throughput plants (<50 t/h) where personnel costs are a large component of costs. • SAB circuits are typically selected for plants of 0.5 to 2 Mt/a.

Fewer mills are, however, easier to control and capital and installation costs are lower, so the number of mills must be decided at the design stage. The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many low-grade, high-tonnage operations such as copper and gold ores feasible.
