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.

Tantalum ore has characteristically grades of about % Ta 2 O 5, generally as a coproduct of cassiterite and other minerals. Note that because of facile overgrinding, metallurgical recovery of columbite by crushing and milling hardrock ore is often as low as 50%. Tantalum is silvery grey, heavy and very hard but malleable and ductile.

Tantalite is named after its tantalum content, and, together with Columbite, are the most important minerals containing the rare element tantalum. The name Tantalite has been discredited by the IMA, with the more specific designations of Tantalite(Fe) (also known as Ferrotantalite ), and Tantalite(Mn) (also known as Manganotantalite ) being used for this mineral's IMAaccepted nomenclature.
