exhibits many of these aspects. Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production (Powell,, van der Westhuizen,, Mainza, 2009). However, SAG mill weight is difficult to control as the dynamic response changes as the mill approaches maximum capacity.

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, semiautogenous grinding (SAG) ballmill circuits represent the single largest type of gold milling comminution circuits, the chapter focuses on SAG.
