Comminution Circuits For Gold Ore Processing Sciencedirect. Jan 01, 2005 The SAG operator who has not been asked to find a way to push ore through the SAG mill is rare indeed As a result, many if not most operators view the SAG mill as a restriction in the grinding circuit that must be overcome, instead of a comminution unit operation required to prepare ball-mill

Jan 01, 2005 For the vast majority of ounces of gold produced, comminution costs in the form of power, grinding media, and liners represent the single largest cost category of milling. Since, semi-autogenous grinding (SAG) ball-mill circuits represent the single largest type of gold milling comminution circuits, the chapter focuses on SAG.
