The Effect of Zinc Oxide Flotation Using Dodecylamine

In this study, the influences of important factors on zinc oxide flotation are investigated. Dosages of sulphidizing reagent, the pH regulator, the activator and the collector, use of sodium sulfide as the sulphidizing reagent, sodium carbonate as the pH regulator, copper sulfate as the activator and dodecylamine as the collector are essential to the effective recovery of zinc oxide. In the closed circuit experiment, these agents showed promising effect, a zinc concentrate with 15.39% Zn was produced with 76.92% recovery as a result of flotation experiment, and in the tailings with 18.56% Zn content.
