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.
