Abstract

See full text

A method ( 100) of producing a neodymium metal can include mixing (1 10) a dissolution agent comprising magnesium with a neodymium-containing feedstock. The dissolution agent and the neodymium-containing feedstock can be heated (120) to an elevated temperature above a melting temperature of the dissolution agent to form a neodymium-magnesium alloy. The neodymium-magnesium alloy can be exposed (130) to hydrogen gas to convert neodymium in the alloy to a. neodymium hydride. The neodymium hydride can be separated (140) from the magnesium in the alloy. The neodymium can be optionally dehydrogenated (150) to yield a purified neodymium product.
