Rare Earths

Scandium (Sc, atomic number 21), yttrium (Y, atomic number 39) and thorium (Th, atomic number 90) are also generally included in the rare earth group because of their similar chemical properties.

Locations of Deposits

Additionally, reserve projections often underestimate the contents of the earth''s crust because lower ore grade deposits may not be considered a reserve (World Nuclear Association, 2012). Demand for elements varies by element group (see Table 1) and the variety of strategic elements results in a similar variety of supply problems.

Rare-earth element

The rare-earth element concentrations are not typically affected by sea and river waters, as rare-earth elements are insoluble and thus have very low concentrations in these fluids. As a result, when a sediment is transported, rare-earth element concentrations are unaffected by the fluid and instead the rock retains the rare-earth element concentration from its source.
