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 20):
The method of  claim 1 , wherein:\n the rare earth metals are selected from the groups consisting of Lanthanum (La), Cerium (Ce), praseodymium (Pr), neodymium (Nd), Promethium (Pm), Samarium (Sm), Europium (Eu), Gadolinium (Gd), Terbium (Tb), Dysprosium (Dy), Holmium (Ho), Erbium (Er), Thulium (Tm), Ytterbium (Yb), Lutetium (Lu), and mixtures or combinations thereof; and the non-rare earth metals or elements (NREMs) are selected from the group consisting of iron (Fe), nickel (Ni), copper (Cu), other transitions metals generally associated with materials that include REMs, boron (B), and mixtures or combinations thereof.
