• Flotation of zinc oxide ores by cationic and mixed

    01/10/2012· 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

    Flotation of zinc oxide afuruika

    The amount of zinc oxide used for flotation varies with the type of ore, but the following amount can be used: Floating zinc oxide ore: sodium sulfide 6~12kg/t,primary amine 100~600g/t. Floating mixed zinc ore: sodium sulfide 1~3kg/t,primary amine 50~100g/t. By this method, the general concentrate grade can reach 40~50%, and the recovery can reach 50~90%.

    Influence of important factors on flotation of zinc oxide

    01/10/2011· The feed to the oxide zinc flotation circuit requires careful desliming prior to flotation, which is then performed with a relatively large amount of sulphidizing agent and a cationic collector, with frother added as required (Hosseini and Forssberg, 2006c). Desliming is essential for successful flotation of smithsonite. Siphon and hydrocyclone desliming methods

    Physicochemical studies of oxide zinc mineral flotation
