Method for obtaining neodymium or neodymium-iron alloy by electrolysis of melts containing neodymium compounds

摘要

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.
