Values for abundances are difficult to determine with much certainty, so all values should be treated with some caution, especially so for the less common elements. Local concentrations of any element can vary from those given here by orders of magnitude. Notes Scandium is never found as the free metal.
Scandium is apparently a much more abundant element in the sun and certain stars than on earth.
However it is widely distributed being present in very small amounts in nearly a thousand different minerals. Most scandium is recovered from thortveitite or is extracted as a by-product from uranium production plants.
