Tantalum mining technique –blasting, crushing, transporting
Tantalum is obtained from minerals like columbite, tantalite and euxenite and is found in combination with niobium. These minerals are found mainly in Australia, Canada, and Brazil. The process of electrolysis is used to separate niobium from tanatalum or reactions of the carbide with oxide.
