  • Selective depression of silicates in phosphate flotation ...

    The hypothesized Hy-PAM role in phosphate flotation is to selectively adsorb on silicates minerals and depress their flotation. Thus, for a better recovery of phosphates, the polymer interaction with phosphate particles should be minimized to allow the selective separation of phosphates from silicates. Therefore, the weaker the polymer/mineral interaction in this case is beneficial in order to ...

  • Use of depressants in the direct flotation of a silicate ...

    Flotation is the most common process; however the selectivity is hampered by the superficial similarity of the chemical composition of phosphates and carbonates, high surface activity of the collectors used, interactions between dissolved ionic species of certain mineral with another and also interactions between dissolved ionic species and reagents. In this study, conducted in a laboratory ...

  • Flotation Reagents - Mineral Processing Metallurgy

    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.
