2) was used for the leaching of rare earths and other metals from ndfeb magnets Technical field [0002] the present invention relates to the field of extraction of rare earth elements (rees), in particular, to a process for extracting rees from a sample that contains rees in metal or alloy form with the use of specific deep eutectic solvents (dess). Deep eutectic solvents (dess), proven to be a unique category of material similar to but separate from ionic liquids (ils), possess many useful properties such as high thermal stability, favorable electrochemical properties, low to no vapor pressure, strong solvation properties, and are environmentally benign. Eutectix manufactures metal alloys, magnetic materials, rare earth alloys, and more for aerospace, automotive, and emerging technologies Electrowinning rare earth elements like neodymium, praseodymium, and didymium, were (obviously) electrowon from their oxides dissolved in fluoride melts Quantum’s unique and patent pending technologies combine the very best uses of photonic, magnetic and rare earth processing and manufacturing, turning the future from solar power to the new frontier of photon power.
