For the mining industry, our semiautogenous (SAG) grinding mill uses a minimal ball charge in the range of 615 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.

This eliminates the need for ultrafine grinding, high temperatures and high pressure which makes it energy saving and very costeffective. In copper, the existing ore bodies are becoming lower grades, they are deeper, and they are more complicated to process. The ROL technology makes it possible to recover more copper from lowgrade concentrates.
