  • Flotation of zinc oxide ores by cationic and mixed

    Oct 01, 2012· 1. Introduction. The flotation of oxidized Pb and Zn minerals, particularly Zn minerals, is much more difficult than the flotation of corresponding sulfide minerals (Hosseini and Forssberg, 2007).The most common flotation technique used commercially for the treatment of ZnO minerals is sulfidization with Na 2 S, followed by treatment with conventional cationic collectors, namely amine Physicochemical studies of oxide zinc mineral flotation,At the present, zinc is produced mostly from zinc sulphide ores because the sulphides are easy to separate from the gangue by conventional flotation techniques. In the case of oxide zinc ores, there is often no selectivity in terms of zinc recovery. The objective of the present study is to investigate the influence of different cationic

    Flotation of zinc oxide ore using cationic and cationic-anionic mixed collectors 151 Armac C. The increase of both collectors dosage increases Zn recovery and decreases Zn grade in the smithsonite flotation concentrate. The reduction of Zn grade is at-tributed to the flotation of more gangue minerals due to high collector concentration. Fig. 6.Zinc smelting Wikipedia,Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific
