  • Anglesite and silver recovery from jarosite residues ...

    15/08/2014  After flotation, the grade and recovery of Pb were 43.89% and 66.86%, respectively, and those of Ag were 1.3 kg/t and 81.60%, respectively. These results prove that the combination of roasting and sulfidization-flotation significantly contributed to the recovery of Zn, Pb, and Ag from jarosite residues in zinc hydrometallurgy.

    Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.
