• Optimising froth condition and recovery for a nickel ore ...

    Recovery of nickel from feed to concentrate in these two minerals is between 76% and 82% and their low nickel content places a restriction on increasing concentrate grade. Mineralogy limits concentrate grade to 7–8% Ni and 5–6% Cu. Pyrite contains little nickel but its recovery to concentrate is far greater than other minerals at %.
