Technical characteristics of tantalum-niobium ore beneficiation. The general chemical formula of niobium tantalite is AB2O6, and the two are collectively referred to as niobium tantalite. A is iron and manganese, and B is niobium and tantalum. The magnetic susceptibility of niobium tantalite is (22.1～37.2)×10-6.
