| Abstract Scope |
Neodymium (Nd) is a valuable element whose demand is increasing with technological development. It is critical for high-performance magnets used in electric vehicles, wind turbines, and advanced electronics. Traditional molten salt electrolysis (MSE) reduction process for neodymium oxide (Nd₂O₃) is environmentally detrimental and energy-intensive, driving demand for more sustainable extraction methods. This study investigates a low-temperature reduction process using magnesium (Mg) as a reducing agent. By exploiting Mg’s reactivity, the process achieves efficient Nd₂O₃ reduction at significantly lower temperatures, reducing energy costs and the environmental impact of high-purity neodymium metal production. High yield and quality are achieved through the optimization of parameters, including temperature, heating rates, Mg stoichiometry, and reaction atmosphere. This method eliminates the need for high-temperature molten salts, minimizing greenhouse gas emissions and enhancing sustainability. The findings provide a scalable and cost-effective alternative for Nd production, addressing the growing need for efficient extraction of rare earth metals. |
