Abstract：The influence of Fe3+ and Fe2+ on the flotation of dolomite, kaolin and quartz with pH change was investigated in presence of sodium oleate.Moreover, the effect of Fe3+ and Fe2+ dosage on mineral flotation under optimum pH condition was also studied.Meanwhile, the effect of Fe3+ and Fe2+ on Zeta potential was analyzed.The results showed that dolomite had good flotation characteristics in sodium oleate system, and the influence of experiments conditions was insignificant.The highest flotation recovery of kaolin was 80% in sodium oleate solution.However, the flotability was not observed in strong-acid and strong-base environments in presence of Fe3+ and Fe2+.Fe3+ could activate the kaolin, while Fe2+ played the inhibition effect.The flotability of quartz was poor, but the highest recovery could be up to 90% after adding Fe3+ and Fe2+ and adjusting pH value.The Zeta potential results proved the results of flotation tests, indicating that the change of Zeta potential was related to the recovery rate.
