Comminution circuits for gold ore processing ScienceDirect

Jan 01, 2005 Publisher Summary. 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.
