ELECTROREFINEMENT OF NEODYMIUM IN CHLORIDE AND CHLORIDE-FLUORIDE MELTS

Relying on the analysis conducted in the paper, the approaches are pro posed for selecting the optimum temperature and cationic composition o f the chloride melt and for determining the advisability of using mixe d-ligand halide melts in the metal electrorefinement. By the example o f neodymium, the efficiency of removing the rare-earth metal admixture s as well as advantages and disadvantages of employing chloride-fluori de melts as compared to chloride melts from the viewpoint of lowering the content of admixtures of such metals-analogues as Y, La, Ce, and P r are shown.
