In the process of processing minerals, grinding uses the greatest energy. Metalliferous ore grinding is frequently the most energy-intensive collection of activities and accounts for around a quarter of the 2% of the world's energy that is used for mineral comminution [2,3]. Ultrafine grinding is the procedure in which the size of the ...
