The Types of Rare and Disperse Scandium Deposits and Prospecting Potential

Scandium is a typical rare and disperse element, and distributes widely in trace amounts in rocks consisting of ferromagnesian minerals. Scandium-concentrated ores are rare in nature, thus the scandium was mainly recovered as a by-product from the ores of monohydrallite, ilmenite, phosphorite, wolframite, tinstone etc. Recently, with the analysis and study on the enrichment experiment of the complex silicate mineral containing scandium, scandium can be extracted from mafic-ultramafic scandium-rich ore bodies containing scandium oxide more than 50×10^-6. The ores of scandium are mainly consisted of clinopyroxene, amphibole. The origin of Ertaipo intrusion is of high scandium, which enters the ferromagnesian minerals during the early fractional crystallization largely to form the new independent deposit, whose Sc₂O₃ is equal to 66.08×10^-6. This kind of deposit is firstly discovered at home and abroad, enlarging the new types of independent deposit and having great significance to the prospecting of Scandium deposit.
