Grinding tests were conducted on an oxidized coppercobalt ore using a pearshaped ball mill. Twelve monosized ore fractions were prepared and wet ground batchwise. The mill was run for to 30 min intervals. The shortest interval provided data more closely related to the breakage function (B) because less secondary breakage was hypothesized.
