sulphide ore flotation

  • Recycle of Wastewater from Lead Zinc Sulfide Ore Flo

    Lead zinc sulphide ore contains lead sulphide (galena), and zinc sulphide (sphalerite). In the first flotation stage, galena is rendered hydrophobic with an organic collector such as xanthate, while sphalerite is kept from floating by depressants, and in the second flotation stage, activator was used to activated zinc flotation.
