  • Optimization of Galena Flotation Process of Irankouh

    The degree of liberation of galena was determined to be 75 microns. To calculate actual density of ore, pycnometer was used and also work index of ore were determined by bond ball mill to find the mechanical behavior and energy consumption in grinding circuit. Actual density and bulk density of ore were 3.0 g/cm 3 and 1.62 g/cm 3, respectively.

  • Galena an overview ScienceDirect Topics

    Galena and chalcopyrite are commonly associated with acid-generating minerals, such as pyrite and pyrrhotite. Acid ferric sulfate solutions, generated through the oxidation of iron sulfides can enhance the oxidation of lead- and copper-bearing sulfide minerals. The oxidation of galena has been studied by Buckley and Woods (1984a), Tossell and Vaughan (1987), Fornasiero et al.
