/il"meuh nuyt'/, n.
a very common black mineral, iron titanate, FeTiO3, occurring in crystals but more commonly massive.

Iron-black, heavy, metallic oxide mineral, composed of iron and titanium oxide (FeTiO3), which is the major source of titanium.

It is found disseminated or in veins in gabbro, diorite, or anorthosite, as in Quebec, New York state, and Norway. It also forms large masses, as in Iron Mountain, Wyoming, and in the Ilmen Mountains, Russia, from which it derives its name. Smaller quantities are present in copper-ore veins, pegmatites, black beach sands, and placer deposits.

      iron-black, heavy, metallic oxide mineral, composed of iron and titanium oxide (FeTiO3), that is used as the major source of titanium. It forms solid-solution series with geikielite and pyrophanite in which magnesium and manganese, respectively, replace iron in the crystal structure. These three minerals are found disseminated or in veins in gabbro, diorite, or anorthosite, as in Quebec, New York, and Norway. Ilmenite also forms large masses, as in Iron Mountain, Wyo., and in the Ilmen Mountains, Russia, from which it derives its name. Smaller quantities are present in copper-ore veins, pegmatites, black beach sands, and placer deposits. For detailed physical properties, see oxide mineral (table).
