Abstract:
Systems and methods for recovering rare earth metals from rare earth metal-containing magnets includes fragmenting or commutating the magnets, contacting the commutated magnets with a mixture of low molecular weight carboxylic acids such as formic acid and water, and removing or extracting non-rare earth metal carboxylate phases such as an iron carboxylate (formate) phase from a rare earth metal carboxylate (formate) phase, using a solvent such as water.

Claim (Index 1):
A method for recovering rare earth metals from waste magnets comprising:\n contacting a rare earth metal-containing magnet material with a reactant composition including a low molecular weight carboxylic acid and water under reaction conditions sufficient to dissolve or extract and concurrently precipitate rare earth metals from the rare earth metal-containing magnet material forming a rare earth metal precipitate including rare earth metal carboxylates and non-rare earth metal components, and removing the non-rare earth metal components from the rare earth metal carboxylates with water to form a purified rare earth metal carboxylate product.
