Nd-Fe-B magnets are widely used in applications such as motors for electric vehicles and hard disk drives, and their demand is expected to increase. In this study, aluminum was used to lower the operating temperature of the high-temperature solvent extraction of neodymium from Nd-Fe-B magnets into bismuth.
