Rutile Is Widely Used In The Optical Industry,
VV Mineral Mining

Rutile is primarily composed of titanium dioxide
(TiO2) and is a mineral found in igneous
environment, sandy beaches and such similar
surroundings.

It is useful in the manufacture of a few optical
elements. It is especially used in polarization
optics, for longer visible and infrared
wavelengths of up to 4.5µm.

Rutile may naturally contain up to 10 iron and
usable amounts of Niobium and Tantalum. It
derives its name from Latin rutilus meaning
red. The mineral displays a deep red colour when
seen by transmitted light.

Rutile is a common accessory mineral in
high-temperature and high-pressure metamorphic
rocks and in igneous rocks. In large enough
quantities in beach sands, Rutile forms an
important constituent of heavy minerals and ore
deposits.

The key uses for Rutile are, manufacture of
refractory ceramic, as a pigment and for the
production of titanium metal.

Finely powdered Rutile is used in white pigments
that require brilliance. Also in paints, foods,
plastics, paper and other applications that call
for a bright white colour.

Nano-sized particles of this red coloured mineral
are transparent to visible light but are highly
effective in the absorption of ultraviolet (UV)
radiation.

The UV absorption of nano-sized Rutile particles
makes them ideal for use in sunscreens to protect
against UV-induced skin damage.
