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

where \(E\) is the processing (by extraction and milling/flotation or leaching) energy usage in MJ per kg of copper concentrate at 30%+ purity or copper in pregnant leach solution. The fixed energy cost parameter \(\beta\) is divided by an ore grade variable \(G\) in percentage of copper per mass of ore extracted, so as to capture changes in energy costs.
