Study on Effect of Complexing Agent Addition on Flotation Index of Copper-Nickel Sulfide Ore

Abstract:

The gangue mineral surface inevitably enriches some copper ions, nickel ions and other metal ions when copper-nickel sulfide ore is ground and in the flotation process. These ions can activate the gangue minerals so as to influence the selective separation of valuable minerals and gangue minerals. This paper, based on the ore property, found that complexing agent LXA could make nickel grade increase to 7.88% from 6.32%, but the recovery rate reduced by 15.61%; complexing agent LXH1 could make nickel grade and recovery rate increase by 0.6% and 1.3% respectively by comparing the flotation effect in the presence of complexing agent EDTA, LXH1, sodium thiosulfate and LXA respectively.
