Tantalite is black to brown in both color and streak.
Occurrence
Tantalite occurs in granitic pegmatites that are rich in rare-elements, and in placer deposits derived from such rocks.
Applications
The tantalum metal extracted from tantalite 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 non-reactive and non-irritating to body tissues. Much like glass, it is not suitable for use in hydrofluoric acid and strong hot alkali applications.[7]
