The ore grades of copper ore being processed around the world have been gradually declining, shown in Figure 2. In the mid‐1800s copper grades were very high, over 10% Cu in Australia and around 8% Cu in Canada, however by 1900 the grades had declined to under 4% Cu.

Benefits include: Reduction in the consumption of neutralising agents used to treat the acidic plant effluents. Improvement in the conservation of raw water resources, with improved water balance. Reduction in plant operating costs. Improved copper cathode income due to an improved leach recovery of about 1 to 1.5% above conventional milling.

Milling is among the most energy-consuming technological stages of copper ore processing. It is performed in mills, which are machines of high rotational masses. The start of a mill filled to capacity requires appropriate solutions that mitigate the overloading. One method for increasing the energy efficiency of ball mills is to optimize their drive systems. This article looks at two variants
