Flotation Separation of Cadmium by Sodium Nitrate-Potassium Iodide-Malachite Green-Water System

Xin Wen

Abstract

The flotation separation behaviour of cadmium by sodium nitrate-potassium iodide-malachite green-water system and the conditions for the separation of cadmium with other metal ions were studied. The results showed that Cd(Ⅱ) can be separated completely from Zn(Ⅱ)?Cu(Ⅱ)? Ni(Ⅱ) ?Mn(Ⅱ)?Fe(Ⅱ)?Co(Ⅱ)?Al(Ⅲ) by flotation at the optimum conditions.
