  • The influence of the impurities on the flotation behaviors

    01-02-2012 · To investigate the effect of three typical impurities (iron copper and cadmium) on the flotation behavior of sphalerite we have synthesized impurity-doped ZnS using a coprecipitation method. In the absence of CuSO 4 the flotation tests show that Cd and Cu impurities greatly improve the recovery of ZnS while Fe impurities apparently decrease the floatability of ZnS.
