The Fe–Mg and Fe–Mn interdiffusion coefficients for ilmenite have been determined as a function of temperature and crystallographic orientation. Diffusion annealing experiments were conducted at 1.5 GPa between 800 and 1100 $$^{circ }hbox {C}$$ ∘ C . For Fe–Mg interdiffusion, each diffusion couple consisted of an ilmenite polycrystal and …
Ilmenite, otherwise called manaccanite, is a titanium-iron oxide mineral with formula: FeTiO3. It is a noteworthy wellspring of titanium. Typically thick and tabular, its crystals sometimes occur as thin lamellae (fine plates) or rhombohedra.. It can also be massive, or occur as scattered grains. Intergrowths with hematite or magnetite are ...
Ilmenite, also known as titanium iron, titanium iron ore or by its synonym menaccanite, is a frequently occurring mineral from the mineral class of "oxides and hydroxides". It …

Ilmenite commonly shows intergrowth with hematite and magnetite. The crystals are totally opaque and appear as thick tabular crystals or anhedral masses embedded in igneous and metamorphic rocks, or as opaque shapeless sand-size grains. Ilmenite is a weakly magnetic mineral. The color is commonly iron-black, brownish-black, with metallic to sub ...
At present approximately 40,000 tons ilmenite, 25000 tons rutile and 1200 tons zircon are produced. In the international market they fetch $240, $1700 and $ 1900 per ton respectively. We now have 565 workers in our factory. To keep them occupied we need 240,000 metric tons of sand to get these minerals.

Ilmenite is a black iron-titanium oxide with a chemical composition of FeTiO 3. Ilmenite is the primary ore of titanium, a metal needed to make a variety of high-performance alloys. Most of the ilmenite mined worldwide is used to manufacture titanium dioxide, TiO 2, an important pigment, whiting, and polishing abrasive. Heavy Mineral Sand ...

Naturally available ilmenite mineral is being used as a starting material to produce titanium based products that have wide applications. Transformation of ilmenite to different titanium based materials by strong and weak acid, and base digestion, is discussed. Effects of temperature, concentration of acid/base, reaction time on dissolution of …

Detrital ilmenite and its altered minerals are common in sandstone-hosted U deposits in the northern Ordos Basin, north China. Petrographic observation, SEM-EDS, EMPA, and LA-MC-ICP-MS were utilized to characterize the spatial relationship between altered ilmenite and the U minerals, and to investigate the U enrichment mechanism and …

[1] We model lunar ilmenite abundances over Mare Australe and Mare Ingenii regions using a new approach; we integrate Lunar Reconnaissance Orbiter Wide Angle Camera (WAC) and Clementine UV-visible/near-infrared (UVVIS/NIR) data to obtain a 14-band mosaic (320-2000 nm). We use Hapke's radiative transfer equations to compute …

Mg-ilmenite inclusions within garnet and clinopyroxene have rounded shapes and size up to 350 μm. Its composition could reflect processes of diffuse equilibration with the host mineral and shows widely range of composition. For instance, Cr2O3 content varies from 2.0 to 7.5 wt.%. The obtained data shows that primary high-Mg ilmenite from the ...
