Abstract
A method of producing a neodymium metal can include mixing a dissolution agent comprising magnesium with a neodymium-containing feedstock. The dissolution agent and the neodymium-containing feedstock can be heated 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 to hydrogen gas to convert neodymium in the alloy to a neodymium hydride. The neodymium hydride can be separated from the magnesium in the alloy. The neodymium can be optionally dehydrogenated to yield a purified neodymium product.
