【Abstract】 Cu(Ⅱ) precipitates in aqueous solution by ammonium thiocyanate and hexadocyltrimethyl ammonium bromide. In the presence of sodium nitrate the precipitates is floatated and Cu(Ⅱ) can be completely separated by floatation even in the presence of Fe(Ⅲ), Al(Ⅲ), Co(Ⅱ), Ni(Ⅱ) and Mn(Ⅱ). The method has advantages covering both the organic and inorganic solvent floatation methods and econimics in surfactants and salts.更多还原
