• TANTALITE (Iron Manganese Tantalum Niobium Oxide)

    Tantalite is the most widespread tantalum mineral and makes for an important ore of the industrially useful metal. Tantalum is used in alloys for strength and higher melting points, in glass to increase the index of refraction, and in surgical steel, as it is nonreactive and nonirritating to body tissues.
