What is Rutile and Its Properties?

Rutile is a naturally occurring mineral composed primarily of titanium dioxide (TiO2), with the chemical formula TiO2. It is one of the three most common naturally occurring crystalline forms of titanium dioxide, the others being anatase and brookite. Rutile crystallizes in the tetragonal crystal system, typically forming prismatic crystals that are often acicular (needle-like) or occur as grains within other rocks. It is generally opaque and has a high refractive index, giving it a distinctive adamantine to metallic lustre, commonly appearing in shades of yellow, reddish-brown, or black. Its hardness is 6 to 6.5 on the Mohs scale, and its specific gravity ranges from 4.18 to 4.25.

Rutile is commercially significant due to its high titanium dioxide content, typically ranging from 94% to over 98% TiO2, making it a preferred feedstock for producing titanium dioxide pigment and titanium metal. While ilmenite (FeTiO3) is more abundant, rutile is often considered a higher-grade ore. It is found in a variety of geological environments, including metamorphic rocks, igneous rocks, and concentrated in placer deposits (mineral sands) resulting from the erosion and weathering of primary sources. The separation and purification of rutile from other heavy minerals in placer deposits are achieved through physical methods like gravity separation, electrostatic separation, and magnetic separation.
