Our experimentally determined ilmenite-melt isotopic fractionations for Fe and Ti indicate that ilmenite would most likely be isotopically lighter than co-existing melt at lunar conditions (e.g., Δ 56 Fe = ilmenite-melt − 0.05 ± 0.02 ‰ and Δ 49 Ti = ilmenite-melt − 0.09 ± 0.03 ‰ at 1100 ∘ C). For Fe, we found that the chemistry of ...

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.
The ilmenite structure is an ordered derivative of the archetype corundum structure. Typically, the ilmenite-type structure is adopted by A 2+ Ti 4+ O 3 compounds when vi R A is much smaller than radius of the oxygen anion resulting in a Goldshmidt tolerance factor, t (Goldschmidt 1926), close to 0.75 (Mitchell 2002).The structure is …

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, IiO2, an important pigment, whiting, and polishing abrasive. Ilmenite has a high resistance to weathering. When rocks containing ilmenite weather, grains of ilmenite ...
Ilmenite as a titanate of ferrous iron mineral (Fe 2 + Ti 4 + O 3) is one of the major TiO 2 containing minerals from which titanium dioxide and titanium metal is …
Physical Properties Of Ilmenite. Ilmenite is a black mineral found in mafic igneous rocks and pegmatites. It belongs to the iron titanium oxide minerals group, which also includes rutile, anatase, brookite, and perovskite. Ilmenite has a hardness of 5.5-6 on the Mohs scale, making it durable enough for use as an abrasive or gemstone polish.
The microstructure of the samples was studied by SEM and the various observed phases were analyzed using the electron microprobe analyzer. The results are given in Fig. 2 and Table 2.Ilmenite analysis showed that the TiO 2 content of the IL-F sample varies from 47.64% to 48.71% (average 48.01%) which is lower than the …

The data indicate that pyrochlores and fersmite are able to strongly fractionate trace elements during the evolution of SiO 2 -undersaturated magmas, and the rare earth element (REE) partition coefficients are around unity, which explains the high rare earth element concentrations in naturally occurring magmatic pyrolores.
Ilmenite is a relatively unaltered grain with a composition close to the theoretical composition, with TiO 2 contents varying between 48 and 53 wt % and a Ti/(Ti + Fe) ratio of 0.5.
