Recycling electronic waste, such as ndfeb magnets, offers a sustainable solution to address the supply chain challenges of rare earth elements (rees) 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. 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). Electrowinning rare earth elements like neodymium, praseodymium, and didymium, were (obviously) electrowon from their oxides dissolved in fluoride melts 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.
