Abstract: We investigate ion exchange equilibria of thiocyanate complexes of gold (I), iron (III), copper (II) and zinc (II) during sorption from individual solutions on anion exchangers AV-17-8, AM-2B and AN-251 (commercial samples made in Russia). It was found out that there is a dependency between the basicity of anion exchangers and the selectivity of gold (I) recovery from thiocyanate multicomponent solutions (at simultaneous presence of Fe (III), Cu (II), Zn (II) and Ag (I) ions). As a result, the sorption sequences for thiocyanate metal complexes were obtained.
