硫酸铵-碘化钾-孔雀石绿体系浮选分离镉(Ⅱ)的研究

Study of the flotation separation of cadmium with ammonium sulfate-potassium iodide-malachite green system

研究了硫酸铵-碘化钾-孔雀石绿体系浮选分离镉(Ⅱ)的行为,探讨了Cd(Ⅱ)与常见离子分离的条件。结果表明,控制水相的pH=3.0,能使Cd(Ⅱ)与Mn(Ⅱ)、Fe(Ⅲ)、Co(Ⅱ)、Ni(Ⅱ)、Zn(Ⅱ)、Al(Ⅲ)、Cr(Ⅲ)很好地分离。

The behavior for flotation separation of cadmium with ammonium sulfate-potassium iodide-malachite green system and the condition for separation of cadmium with other metal ion were studied. The result showed that CA（N） could be separated from Mn（Ⅱ）,Fe（Ⅲ）,Co（Ⅱ）, Ni（Ⅱ）,Zn（Ⅱ）,AI（Ⅲ）,Cr（Ⅲ） at pH 3.0.
