Abstract
The separation of cadmium(II) from aqueous solutions by a precipitate flotation technique using sodium sulfide as a precipitant and oleic acid (HOL) as a surfactant has been investigated. The effects of HOL and sodium sulfide concentrations, pH, addition of some ions, ionic strength, temperature, and order of reagents addition on flotation efficiency have been studied. A 100% floatability of Cd(II) was obtained at pH 5.5–6.5. It was found that the order of reagents addition markedly affects the flotation of Cd(II).Keywords
