  • Study on the Interaction between Galena and Sphalerite

    In Pb–Zn ore flotation unintentional activation of sphalerite often leads to difficult separation of Pb and Zn minerals during which grinding plays a key role in unintentional activation. Therefore the aim of this study was to evaluate the surface component changes of two different mineral particles and to propose the interaction between galena and sphalerite during mixed grinding using

  • Zinc sulphate addition point (Pb/Zn flotation)Froth

    In this case activated sphalerite is not a problem. NaCN should be added in the grinding circuit (e.g. 20-30 g/t). In some cases operations add Sodium Metabisulphite (e.g.100 g/t) to improve the depressing action on pyrite and sphalerite. The best way to evaluate the
