Mining energy consumption contributes to mining operational costs and occurs at all stages of the ore recovery process: blasting, excavation, crushing, transport and grinding (comminution). For example, the copper mining industry is expected to consume 41.1 terawatt-hours (TWh) in 2025, an increase of 95.5 percent from 2013 [11].
