What is tantalite used
for?
Coltan is a dull black metallic ore from
which the elements niobium and tantalum are extracted. The
niobium-dominant mineral in coltan is columbite, and the
tantalum-dominant mineral is the tantalite.
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 non-reactive and non-irritating to body
tissues.
