Scandium in oxide form is referred to as scandia or scandium oxide, and the chemical formula is Sc2O3. Processed scandium oxide, a white powder, is stable at ambient temperature and is the standard scandium form for commerce.
This scandium recovery process includes a washing step (S1) for washing a neutralization sediment (drainage sediment) and a dissolution step (S2) for subjecting the washed sediment obtained in the washing step (S1) to dissolution in an acid.
By processing 10 kg of euxenite and other residues of rare-earth minerals, Nilson was able to prepare about 2g of highly pure scandium oxide. Later scientists pointed out that Nilson's scandium was identical with Mendeleev's ekaboron.
scandium mine in operation in the world. The mine has a proven minable scandium reserve of 7.58 million t of ore grading at 1.5 g/t of scandium, likely to yield 907,185 t of final Al-Sc product.
