【Abstract】 In the aqueous solution, Cu(Ⅱ) precipitates with ammonium thiocyanate and tetradecyl benzyl dimethylammonium chloride. I n the presence of sodium chloride, the precipitates are floated out. It has been showed that Cu(Ⅱ) can be isolated from other metal ions such as Fe(Ⅲ), Co(Ⅱ), Ni(Ⅱ), Mn(Ⅱ) and Al(Ⅲ) by floatation. Compared with the traditional floatation that uses organic extracts, this process has the advantages of being simple, non toxic and economic.更多还原
