In addition, the size distribution and grinding circuit chemistry may impact on the performance of the downstream circuit (Lane, 1999 and Rantanen, 1996). Fully autogenous circuits are attractive due to the elimination of steel media costs. Typically, a SAG mill based circuit (P80 of 106 to 150 um) has media costs of around A$1/t.

When ore becomes rounded in most AG/SAG mills, comminution rates may be reduced in proportion to the relative size and quantity of rounded edges. Recycle crushers not only minimize critical size fractions but also place edges on rock to promote comminution in AG and SAG mills. Mill design and PBM models must account for this condition.
