| Abstract: | The extraction of Fe, Zn and In by La2HCl from H2SO4 solutions has been studied. The formation of the aqueous complexes H2Fe(SO4)2HSO4, HZn(SO4)HSO4 and HInSO4(HSO4)2 is discussed. The formation of mixed ligand species H2Fe(SO4)2Cl, HZnSO4Cl and HInSO4Cl2 from the interaction of Cl+ in aqueous solution or in LA2HCl before extraction is explained. The reactions in the system to produce the extractable species are discussed. The possible separations are given. |
