Abstract (en)
[origin: US5346608A] Neodymium and neodymium-iron alloys are obtained by electrolysis of a neodymium salt melt using magnetite as the anode material. The cathode is non-consumable or is made of iron to be consumed and form a neodymium-iron alloy. The electrolysis is preferably carried out under a protective atmosphere.
