This plant uses a vertical stirred mill after AG rather than a ball mill to achieve this fine grind size with an energy cost saving of 35% or better (Arvidson, 2013). An important part of the comminution circuit is size classification. This can be accomplished with screens or cyclones or a combination of the two.
