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. The sequential flotation circuit, as shown in Figures 2,3 and 4,
