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

Changes in metal prices and mine output over recent years have required the Copper Concentrator of Mount Isa Mines to operate at annual tonnage rates varying from 4.0 million to 6.5 million tonnes. Several circuit combinations were operated during this period utilising up to two semi-autogenous grinding (SAG) mills and up to two ball mills. The aim was to maximise

2016-6-18 The ore then passes into a two-stage grinding circuit, consisting of two parallel primary ball mills and two parallel secondary ball mills, as shown in Figure 1. The target grind size for this circuit is 75 µm. The slurry subsequently enters a single thickener in order to achieve the optimum flotation feed density of 46 per cent solids.
