Extraction and optimization of neodymium from molten fluoride electrolysis

Most rare earth elements (REEs) are critical materials of extreme prominence. Because their criticality, convalescence into metal from oxide (REO) and recycling end-of-life essential for the proficient use safeguard natural resources. With pyrometallurgical approaches using potential versus partial oxidation pressure (E-pO2-) diagrams, conditions making neodymium established by which REOs dissolved in a molten halide bath to form pure Nd electrolysis process. This paper also expands on how diagrams used verified through design experiment studies, result statistical rejoin models based salt extracting its fluoride bath.
