    Abstract: The present invention discloses a method for recovering rare earth particulate material from an assembly comprising a rare earth magnet and comprises the steps of exposing the assembly to hydrogen gas to effect hydrogen decrepitation of the rare earth magnet to produce a rare earth particulate material, and separating the rare earth particulate material from the rest of the assembly.The invention also resides in an apparatus for separating rare earth particulate material from an assembly comprising a rare earth magnet. The apparatus comprises a reaction vessel having an opening which can be closed to form a gas-tight seal, a separator for separating the rare earth particulate material from the assembly, and a collector for collecting the rare earth particulate material. The reaction vessel is connected to a vacuum pump and a gas control system, and the gas control system controls the supply of hydrogen gas to the reaction vessel.

    Abstract translation: 本发明公开了一种从包含稀土磁体的组件中回收稀土颗粒材料的方法，包括以下步骤：将组件暴露于氢气中，以实现稀土磁体的氢气爆裂以产生稀土颗粒材料，并分离 来自组件的其余部分的稀土颗粒材料。 本发明还涉及一种用于从包含稀土磁体的组件中分离稀土颗粒材料的设备。 该装置包括具有可以封闭以形成气密密封的开口的反应容器，用于从组件中分离稀土颗粒材料的分离器和用于收集稀土颗粒材料的收集器。 反应容器连接到真空泵和气体控制系统，气体控制系统控制向反应容器供应氢气。

    Abstract: A process is provided for the production of rare earth magnets comprising the steps of exposing a rare earth alloy to hydrogen gas at an elevated temperature so as to effect hydrogenation and disproportionation of the alloy, mechanically processing the disproportionated alloy, and degassing the processed alloy so as to effect hydrogen desorption and recombination of the alloy. The process of the invention finds use in the production and shaping of rare earth magnets, and may be particularly applicable to the production of thin magnetic sheets.
