| 简介 |
A method for recovering rare earth particulate material from an assembly (46) comprising a rare earth magnet comprises the steps of exposing the assembly to hydrogen gas to effect hydrogen decrepitation of the rare earth magnet whereby a rare earth particulate material (48) is produced, and separating the rare earth particulate material from the rest of the assembly. Apparatus (10) for use with the method comprises a reaction vessel (12) having an opening (18) which can be closed to form a gas-tight seal, a separation means for separating the rare earth particulate material from the assembly (46) and a collection means (24) for collecting the rare earth particulate material. The method and apparatus find application in the recovery and recycling of rare earth magnets from assemblies 46 such as electronic devices. |
