2. Background. The SAG grinding process has been modeled by various authors, either generating explanatory models of the grinding process, with the aim of modeling, simulating, and optimizing the individual process, as well as integrating it into aggregate processes, such as the minetomill (M2M) paradigm, a practice that has generated the capacity to analytically assess aspects of mining and ...
