The growing global demand for rare earth elements (REEs), driven by their critical applications in advanced technologies, has significantly intensified efforts to recover these valuable resources from end-of-life NdFeB magnets. This research proposes a comprehensive, market-oriented method for REE recovery involving the dissolution of metals using organic acids, followed by their selective separation to produce high-purity REE oxides. The approach addresses critical environmental and economic considerations by minimizing waste generation and optimizing resource efficiency. Experimental results demonstrate that the developed process efficiently separates REEs and iron with high recovery rates and exceptional purity. The process was patented and used in a pilot plant designed for the New-RE project. Upscaling the first industrial plant in Europe to recover rare earth from end-of-life NdFeB magnets is underway within the European INSPIREE project. This innovative methodology represents a pivotal step toward sustainable development by reducing reliance on primary mining operations, promoting circular economy principles, and decreasing dependence on REE imports from non-EU countries. Such advancements highlight the potential for achieving resource security and fostering greener industrial practices.
