Solvent extraction of Pr and Nd from chloride solution was carried out using PC 88A for the recovery of magnetic grade Nd. The presence of complexing reagents (H2O2 and citric acid) affected little the selective extraction of Nd over Pr. The observedmaximum separation factor between Pr and Nd was 1.5, indicating that the separation of Nd and Pr by selective extraction was difficult. Co-extraction of two metals with PC 88A followed by selective scrubbing was tried. Batch simulation of counter-current showed that the complete recovery of Nd was possible and a process flow sheet has been presented.
