  • advantage of zinc sulfate flotation

    Flotation techniques (most frequently used zinc sulfate or Sheather's sugar) use solutions which have higher specific gravity than the organisms to be floated so that the organisms rise to the top and the debris sinks to the bottom The main advantage of this technique is to produce a cleaner material than the sedimentation technique Get Price
