    Dec 10, 2017· Dextran sulfate sodium has a depressant effect on flotation of calcite and fluorite when sodium oleate is used as a collector. The preferential flotation separation of scheelite from calcite and fluorite can be realized when dextran sulfate sodium is added before sodium oleate by

  • Separation of Sodium Sulfate by the Flotation Method

    Jun 26, 2017· The flotation characteristics of pure sodium sulfate crystal in the saturated solution with both sodium sulfate and sodium chloride were examined. On the basis of results obtained, separations of sodium sulfate from the recovered salts, which prepared from the imitative electrolyte, were carried out by using a FW-50 type flotation test machine.
