  • Extraction of Zinc QS Study

    Extraction of Zinc . Zinc blende is concentrated by floath floatation process. The pulverized ore is kept in large tank containing water and pine oil. The mixture is agitated by passing compressed air. Ore forms froth and comes to the surface while impurities are left in water. Zinc Blende does not contain a very high percentage of zinc and hence it needs to be concentrated. The best
