Extraction of scandium from bauxite residue by high …
Ochsenkühn-Petropulu et al. showed that 29–96% of REEs in bauxite residue could be extracted by direct leaching using 0.5 M nitric acid, at the liquid to solid ratio of 50, the retention time of 24h, and at room temperature. Under this condition, a scandium extraction of 83.8% was obtained, with co-extracted iron of 2.2%.
