Flotation Tests of Zinc Oxide Ore with Iron

Abstract:

Flotation tests for recovering zinc and iron from gossan ores was carried out in this paper. Flotation is the most commonly used method for beneficiation and pretreatment of oxidized zinc minerals. The effects of grinding fineness, amount of Na₂CO₃, amount of Na₂SiO₃, amount of Na₂S and amount of octadecylamine were investigated, respectively. The results show that the grade of zinc and iron increase slightly, and the best result is that the grade of zinc and iron are 13.12% and 41.15%, the recovery of zinc and iron are 76.83% and 77.95%. The results simply indicated that flotation could not effectively recover zinc and iron from gossan ores studied in this paper.
