Selective Dissolution of Nd<sub>2</sub>O<sub>3</sub> from the Mixture with Fe<sub>2</sub>O<sub>3</sub> and Ga<sub>2</sub>O<sub>3</sub> by Using Inorganic Acid Solutions Containing Ethylene Glycol

Rare earth elements (REEs) are strategically critical in the manufacture of advanced materials. Red mud and end-of-life NdFeB magnets can be good secondary sources for REEs, but recovery is difficult due to the high iron oxide content and small amount of REEs. Oxide mixtures whose composition of Fe,...
