Rare earth elements (REEs) were discovered in Sweden in the 18th century (Dushyantha et al., 2020). REEs are defined by the International Union of Pure and Applied Chemistry (IUPAC) as a general name of 17 metal elements in the periodic table, including 15 lanthanides together with scandium (Sc) and yttrium (Y) (Damhus et al., 2005, Erust et al., 2023).

The ionic radii of the lanthanide [M] 3+ ions is shown in Fig. 1 along with the ionic radius of the trivalent ions of yttrium and scandium (Gupta and Krishnamurthy, 2005). Their similarity in ionic radii means that the rare earth elements are interchangeable in most minerals and are consequently very difficult to separate (Gupta and Krishnamurthy, 2005).

The distribution of rare earth elements varies significantly between rare earth ores and ionic clay deposits. This distinction is evident in Table 1 (Packey and Kingsnorth, 2016). Table 1 highlights that ionic clays have a higher presence of heavier rare earth elements, ranging from gadolinium oxide (Gd 2 O 3) to lutetium oxide (Lu 2 O 3), including yttrium oxide (Y 2 O 3).
