Comminution circuits for gold ore processing

2005-1-1  Unlike ball-mill circuits, it can be very difficult operationally to trade grind for throughput in a SAG circuit. Once designed and constructed for a given ore type, a SAG mill circuit has only limited flexibility to deliver varying product sizes. This is particularly true for those SAG circuits designed with a coarse closing size.
