Title: Process for recycling rare earth magnets

Abstract

A method to separate rare earth material from a rare earth magnet. At least one embodiment comprises a method that heats a provided rare earth magnet to at least 600° C. whereby the rare earth magnet absorbs a dry gas. Separated rare earth materials are created. Magnetic rare earth materials are produced from the separated rare earth materials.
