Area of application: It is used in many popular consumer products, such as televisions and fluorescent or energy-saving lamps. In industry, the primary use of scandium is to strengthen metal compounds.
SELECTION OF METHODS FOR SEPARATING OF SCANDIUM MINERALS
During the processing of minerals containing scandium, plants use the following types of separation:
Scandium is extracted as a byproduct from slag (Sc2O3 0,01-0,5 %):
Bauxite (Al)
Wolframite (W)
Cassiterite (Sn)
Fe
V
Scandium can be extracted from hard coal and Laterite.
