Resumen: © 2017 Society of Chemical Industry BACKGROUND: Recovering Nd(III) from waste magnets is an alternative method to satisfy the increasing demand for this metal. For this reason, the separation of Nd from a mixture containing Nd/Tb/Dy in chloride media using Cyanex 272 and Cyanex 572 has been evaluated. RESULTS: Using Cyanex 272 and Cyanex 572, the metals are transported in the order Dy(III) > Tb(III) > > Nd(III) in all conditions studied. The optimum feed conditions to achieve Nd(III) separation are: Cyanex 272: pH 2 and Cyanex 572: pH 1.5 with 1.2 mol L-1 HCl as a receiving agent for both carriers. CONCLUSION: The results obtained suggest that Cyanex 572 is a better carrier than Cyanex 272 for separating Nd(III) from a mixture containing Nd/Tb/Dy. © 2017 Society of Chemical Industry.
