Abstract

A process for separating molten metals, the molten metals being treated with metal hydrides is provided. The molten metals employed are from Groups II-IV of the Periodic Table of Elements and the subgroups, including their alloys, and are distinguished by the fact that the metals or alloys are reacted with a metal hydride in a molten bath.
