Tantalum— the Earth’s 49th most abundant element— is frequently produced as a by-product of tin smelting. The metal is also extracted from concentrates by reduction with sodium or fused-salt electrolysis; tantalum carbide is produced by carburization of Ta2O5 or tantalum hydride. Sintering, electric-arc melting and electron-beam melting are used to refine and purify raw tantalum.
