Waste rocks occupy space from ore in the grinding mill, thus lowering the mill's ore grinding capacity and mineral concentrator's concentrate production. Moreover, in most cases, waste rock is harder and, consequently, more difficult to grind than the ore which is often found in the weaker areas of the rock.
