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.
