Grinding is often finished with a ball mill, which differs from a SAG mill, as it relies on the steel alone for grinding. A SAG mill may have 10% steel where a ball mill will typically have 30%. Classification is normally carried out in hydro cyclones with the product feeding either a flotation or leach circuit.
