  • The Application Of Xanthate In Froth Flotation Process

    The surface of galena is hydrophobic, so it’s easy for flotation. Xanthate is the common collector for the flotation of galena. When the pH is high, the galena is easily floated by the ethyl xanthate. The optimum pH for flotation is 7-8, which can usually be adjusted with sodium carbonate. The above describes the application of xanthate in

    Optimum galena flotation seems to indicate that the main role of the hydrosulfide is to react with aqueous lead dissolved from the mineral and with oxidized surface sites (Gebhardt and Kotlyar, 1991).

    The floatability of pyrite is similar to galena under low pH condition, which is harmful to the separation of galena from sulfur minerals. However, the galena will be depressed as well as pyrite if the pH is too high . Thus, the pH value of the flotation pulp should be neither too high nor too low.
