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.
