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.

Process for the recovery of rare earth metals from permanent magnets

Methods and systems for recovering or extracting rare earth elements under mild conditions include subjecting a material including rare earth element to a rare earth element crystallization medium under solvothermal conditions sufficient to form rare earth element crystals capable of gravity separation and purification.
