The effect of sulphite ions on the xanthate-induced flotation of copper-activated pyrite has been studied. Various techniques have been used to identify the plausible mechanisms of interaction of sulphite with both collector and pyrite surface. It was f ound that sulphite depressed the xanthateinduced flotation of copper-activated pyrite with nitrogen or air purging at pH 7. However, the depression effect was greater when air was used. Solution and spectroscopic studies indicated that sodium… Expand
