scandium ore associated


Scandium | Geoscience Australia

Scandium in the environment. Scandium can rarely be found in nature, as it occurs in very small amounts. Scandium is usually found only in two different kinds of ores. Thortveitite is the primary source of scandium with uranium mill tailings by-products also being an important source. World production amount to only 50 kg per year.
