  • Publication number: 20240093399
    Abstract: Provided is a method for electrowinning neodymium compound. The method includes providing a fluoride-based electrolyte through an opening defined in an electrolytic bath including a cathode and an anode. The method includes providing granules, each including a neodymium compound and having at least one cavity defined therein, through the opening defined in the electrolytic bath. The method includes dissolving at least a portion of the granule in a molten salt of the fluoride-based electrolyte. The method also includes reducing neodymium at the cathode. The cavity is defined inside or on the surface of the granule, and the apparent density of the granules is lower than the density of the molten salt. The method proposed has an improved process compared to those of the related art.
