A review of zinc oxide mineral beneficiation using flotation
The flotation of zinc oxide minerals is suggested for sulfidization of the smithsonite followed by activation with CuSO 4 and flotation of the activated zinc oxide using xanthate at pH 10.5 [13]. It is also implied that after pretreatment of the pulp with sulfidizer followed by reconditioning with CuSO 4,zinc oxide flotation can be achieved A representative sample of zinc oxide from Dashteh Sefid mine was obtained and then mineral characterization studies were done. The results of mineralogical analysis showed that the main zinc-bearing minerals are smithsonite, hemimorphite and gangue minerals are quartz and dolomite. In the present paper, the effect of important Flotation study of oxide zinc ore using cationic-anionic mixed

Testing of 17-different leaching agents for the recovery of zinc
Cinkur lead–zinc plant was started in 1976 in Kayseri, Turkey, which could produce 35,000 tpy zinc, 6000 tpy lead along with 4.5 tpy silver and 125 tpy cadmium from oxide-carbonated zinc-based metals using the Waelz process (Roast-Leach-Electrowinning-RLE). Due to economic reasons, the plant was shut down in 1999.Sphalerite is a common sulfide mineral, and xanthate is usually used as the collector of sphalerite flotation. In order to realize the simultaneous flotation of sphalerite- and zinc-containing oxide ores, in this paper, dodecylamine was used as the collector and sodium sulfide as the regulator to explore the flotation behavior of Flotation Mechanism of Sphalerite by Sulfuration–Amine Method
