Energy in the copper mining industry is needed in three forms namely: electricity, heat, and fuel. The share of each form of energy is 35% electricity, 26% Dieselfuel, and 20% biomassfuel. The cost of energy is currently high and represents about 2530% of total operating costs ( Cochilco, 2020 ).

The underflow is sent to a secondary ball mill and trommel screen, for additional grinding and classification. Using froth flotation, the copper minerals separate from the gangue and rise to the froth layer of the flotation cell. In turn, the copperrich bubbles are removed or transferred to the next stage of flotation for further processing.

Energy costs typically comprise one of the largest ongoing costs of mining operations, of which 70% is devoted to the comminution of the ore (Norgate and Jahanshahi, 2010). Furthermore, the most significant energy cost occurs in the grinding circuit of the Milling section, where up to 97% of the energy cost is incurred (Ballantyne et al., 2012).
