• Overview On Extraction and Separation of Rare Earth Elements from Red Mud: Focus on Scandium (2018, background): “Total extraction of yttrium, lanthanum, cerium, neodymium and dysprosium was 85–95% (Borra et al., 2015b).”
• Selective recovery of rare earths from bauxite residue by combination of sulfation, roasting and leaching (2016, background): “That could be the reason for the poor scandium extraction since scandium(III) oxide is locked in the iron(III) oxide lattice (Borra et al., 2015; Brookins et al., 1983).”
• Extraction of rare earths from bauxite residue (red mud) by dry digestion followed by water leaching (2018, background): “1), and even much lower than the values reported in the literature (Borra et al., 2015b; Rivera et al., 2017).”
• Metallurgical process for valuable elements recovery from red mud—A review (2015, background): “…addition to the occurrence of scandium and gallium in the red mud, it still contains tiny amounts but valuable of other rare earths and radioactive elements, for instance, yttrium (60–150 g·t−1), uranium (50–60 g·t−1), thorium (20–30 g·t−1), etc. (Borra et al., 2014; Smirnov and Molchanova, 1997).”
• The Rare Earth Elements: Demand, Global Resources, and Challenges for Resourcing Future Generations (2018, background): “These bauxites and associated red mud waste products thus have the potential to contain significant REE resources (Wang et al. 2010; Boni et al. 2013; Deady et al. 2016), and research is ongoing to develop processes for extraction of REE (Borra et al. 2015).”
