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 11):
A system comprising:\n a reaction vessel including a rare earth metal containing-magnet material input connect to a rare earth metal containing-magnet material source, a low molecular weight carboxylic acid input connected to a low molecular weight carboxylic acid source, a water input connected to a water source, a waste liquid outlet connected to a waste liquid receiver and a rare earth metal product outlet connected to a rare earth metal product receiver, where an amount of the rare earth metal containing-magnet material, the low molecular weight carboxylic acid and the water are added to the reaction vessel to form a reaction mixture and the reaction mixture is held under reaction conditions sufficient to dissolve or extract the rare earth metals to form rare earth metal carboxylates along with non-rare earth metal carboxylate hydrates that precipitate out of the reaction mixture, and a separating vessel to separate the precipitate from the liquid and to wash the precipitate with a solvent to remove the non-rare earth metal carboxylate hydrates to form a purified rare earth carboxylate product.
