| 摘要 |
<p>The present invention relates to a recirculation system of an NdFeB-based magnet using molten Mg including an elution step for eluting Nd by submerging NdFeB-based magnet scraps or waste magnets in molten Mg; a separation step for separating the molten Mg including the Nd from a solid residue; and a manufacturing step for manufacturing an Mg-Nd-based amorphous metallic material using an Mg-Nd alloy manufactured in the separated molten Mg. The recirculation system of NdFeB-based magnet can control the weight ratio of the Mg-Nd alloy by controlling the elution step based on the weight ratio of Mg and Nd included in the Mg-Nd-based amorphous metallic material. The present invention can recycle Nd included in the NdFeB-based magnet without an additional process of separating the Nd from the molten Mg by using the molten Mg containing the Nd generated in the recirculation process of the NdFeB-based magnet. Also, the present invention can recycle a Fe-B solid material remaining after the Nd is eluted without a separation process.</p> |
