Flotation Separation of Zinc(Ⅱ) by Sodium Chloride-Ammonium Thiocyanate-Cetylpyridinium Chloride-Water System
Abstract:
The flotation separation behaviour of zinc(Ⅱ) by sodium chloride-ammonium thiocyanate-cetylpyridinium chloride(CPC)-water system and the separation conditions for zinc(Ⅱ) with other metal ions have been studied. The results showed that in the presence of 1.0 g solid NaCl, 2.0 mL NH4SCN(0.1 mol/L) and CPC(0.01 mol/L), Zn(Ⅱ) could be separated completely in a mixture solution (pH=4.0) containing Cd(Ⅱ)、Co(Ⅱ)、Ni(Ⅱ)、Mn(Ⅱ)、Fe(Ⅱ)and Al(Ⅲ) by flotation process. The method was used in separation of Zn(Ⅱ) in synthetic multiple ion mixture solution with satisfactory result.
