Copper Concentrator Autogenous Grinding Practices at

The next step in the evolution of the grinding circuit at the copper concentrator is to remove one ball mill from the secondary grind- ing circuit whilst maintaining the current production budget of 6.0 Mtpa. This will result in a coarser flotation feed size, probably making the flotation feed sizing slightly coarser than in the original
