Ore is reclaimed via apron feeders onto a conveyor belt providing direct feed, at a rate of about 2,500t/h, into the 38ft × 18ft SAG mill. The SAG mill trommel undersize discharges into a hopper and is pumped to conventional hydrocyclones, operating in closed circuit with a 26ft × 40ft ball mill. The hydrocyclone overflow (P80 of 280µm) reports to flotation, while the underflow returns to

Ore is stored in a 3,175t silo before being fed to a SAG mill. Oversize is passed to a ball mill while undersize is cycled to flash flotation circuits. The float product is thickened, the concentrate containing 1,700g/t PGM. Tailings from the flash flotation are fed to hydrocyclones and the overflow is fed via conditioner tanks to the rougher/scavenger/cleaner flotation circuits.

SAG mills are characterized by their large diameter and short length as compared to ball mills. The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge. SAG mills are primarily used at gold, copper and platinum mines with applications also in the lead, zinc, silver, alumina and nickel industries.
