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).
