Tantalum oxide is the main material used for production of tantalum carbide and tantalum metal. In Russia, cerium-bearing mineral is processed by the chlorination process. The tantalum in ore is chlorinated, vaporized, and condensed to generate tantalic chloride. Then after hydrolysis, washing, filtration, and roasting, tantalum oxide is obtained.
