Comminution circuits for gold ore processing
Since, semi-autogenous grinding (SAG) ball-mill circuits represent the single largest type of gold milling comminution circuits, the chapter focuses on SAG. At mines, where ore has become more competent during the life of the mine (and ore rarely gets softer as the mines go deeper) or at operations, where the SAG mill was undersized during design, operators find themselves limited by a SAG

Ore Processing Challenges in Gold Operation Grinding Circuits
Comminution circuits are used to optimize the liberation of valuable mineral particles from waste rock for downstream separation processes. When the target grind is not achieved (under-grinding), it results in a higher number of unliberated gold particles. This in turn causes a loss in gold recovery and therefore revenue. Over-grinding does not have a significant benefit to gold recovery but
