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).
