| Abstract: | The flotation separation behaviour of cobalt with NH4SCN-CV(crystal violet)-H2O system and the conditions for separation of cobalt from other metal ions were studied. In the aqueous solution, Co(Ⅱ) was precipitated by reaction with thiocyanate and crystal violet, and the precipitate could be separated from aqueous solution by filtering. Under the optional conditions, the completely separation of Co(Ⅱ) from Zn(Ⅱ), Fe(Ⅲ), Cd(Ⅱ), Ni(Ⅱ), Mn(Ⅱ), Al(Ⅲ) was realized by floatation at pH 1.0～2.0. |
