Ilmenite is an iron titanium oxide which is the principal ore of titanium. The chemical formula of ilmenite is FeTiO3.Black or dark gray in colour, it has a metallic luster and is usually weakly magnetic. While the mineral itself is actually not magnetic, it is often intergrown with magnetite which is strongly magnetic.
Ilmenite and magnetite are opaque minerals and can be differentiated from each other by the crystal structure. Magnetite is an isometric mineral and forms double pyramids (octahedrons) just like those of diamond. These octahedrons are often worn off in sand but magnetite is rounded and still roughly isometric.
Ilmenite grains tend to be tabular and the crystal structure of ilmenite is identical to hematite. It is also compositionally close to hematite ; the only difference between them being that one Fe atom (in hematite) is replaced by titanium atom (in ilmenite).
At Maxworth Minerals, we supply Ilmenite in bulk quantity as per customer end requirements, mostly for use in the paints, fabrics, plastics, paper, sunscreen, food and cosmetics industries (as a source of titanium dioxide.)
