widely in copper ore autogenous mill

2019-1-28  However, some Swedish fully autogenous mills are so equipped and recently Afton Mines in British Columbia commissioned an autogenous mill with variable drive. Most SAG operations use volumetric ball charges, i.e., % of mill volume occupied by the balls including interstitial volume, of 6-10% depending on the work index of the ore
