Comminution circuits for gold ore processing -

2005-1-1  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 mill's
