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). Indeed, the area of comminution, and particularly grinding, are flagged as areas where significant savings can be made in mineral processing circuits (Evans et al., 2009).

Crushing and milling. Mineral processing usually requires reducing the particle size of the ore, a process called comminution followed by separating ore and gangue minerals and concentrating ore minerals. The mined ore is tipped into a crusher crushing the blasted rock from the mine to smaller pieces, usually the of small stones or gravel.
