Copper Ore Crushing, Grinding Flotation
21/05/2017 The attraction of semi-autogenous grinding in copper operations is that they can accommodate ores that are hard or soft, wet or dry, sticky or otherwise. The SAG mill can handle everything that is presented to it, regardless of coarseness or fineness, or hardness or moisture content, and from it prepare satisfactory feed for subsequent secondary grinding by conventional means to the required flotation product sizing. A parallel point not to be forgotten is that the SAG

SAG Mill Grinding Circuit Design - 911metallurgist
06/06/2016 AG/SAG mills grind ore through impact breakage, attrition breakage, and abrasion of the ore serving as media. Autogenous circuits require an ore of suitable competency (or fractions within the ore of suitable competency) to serve as media. SAG circuits may employ low to relatively high ball charges (ranging from 2% to 22%, expressed as volumetric mill filling) to augment autogenous media.
