pyrite in zinc ore flotation

  • Selective separation of galena and sphalerite from pyrite

    pre-flotation which is a flotation stage prior to the galena flotation is employed to remove part of the organic carbon. Following the pre-flotation stage lead and zinc sulfides are floated in separate circuits and during the flotation process pyrite is floated to the concentrates.

    Sodium silicate was somewhat effective in causing a differential or selective flotation of copper as chalcopyrite from pyrite by keeping pyrite from floating. Sodium hydroxide and sodium sulfide gave in most cases a distinct separation of sphalerite from chalcopyrite i.e. a high copper and low zinc by suppressing the flotation of sphalerite.
