Scandium does not form its own deposits. Scandium minerals, thortveitite (Sc 2 [Si 2 O 7]) and sterrettite (ScPO 4 2H 2 O), are very uncommon and have no commercial significance. Minerals, in which scandium is present in the form of isomorphous admixtures with concentration of Sc 2 O 3 ranging from 0.005 to 0.3%, are more extensive.
