The formation of rare earths is diverse and complex. They do not occur as native elemental metals; instead, they are seen in various host minerals, such as halides, carbonates, oxides, phosphates, and silicates (Rim et al., 2013, Suli et al., 2017).Due to the similarities in their ionic radii, the rare earths can interchange with other minerals, making their concentration …
