flotation of zinc oxide ore

  • Flotation of zinc oxide ores by cationic and mixed

    1/10/2012· In Dandy processing plant, Zanjan, Iran, the tailing of cerrusite flotation is Zn concentrate containing 20–25% Zn which is leached by sulfuric acid to extract the Zn metal. In recent years, by decreasing the Zn content of the ore, the upgrade of tailing by froth flotation before acid leaching has become considerably attractive.
