The commercial processes to extract iron from ilmenite (FeTiO 3 ) essentially include energy-intensive methods, such as high-temperature reduction smelting or preoxidation, coupled with reduction by carbon. However, due to altered mineralogy of ilmenite caused by weathering at sea coast, the reduction of iron remains incomplete in either of these processes, demanding a high concentration of ...
Oxygen and metallic iron are produced from an iron oxide-containing mineral, such as ilmenite, by extract ing iron from the mineral with hydrochloric acid, sepa rating solid residue from the resulting solution and dry ing same, electrolyzing the separated, iron chloride- containing solution to produce electrolytic iron and
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 …
A set of mesoporous delaminated montmorillonites containing iron(III)-titanium oxide species was synthesized using two minerals: a bentonite as support and an ilmenite as source of Fe-TiO2 species. Several values of both sulphuric acid concentration and temperature were employed to extract Fe-TiO2 species from an ilmenite.
demand for the other feedstocks such as ilmenite has gained increasing attention. However, both ilmenite (FeTiO 3) and leucoxene (Fe 2O 3.nTiO 2) contain signifi-cant amounts of iron. The TiO 2 content in ilmenite, which may range from 40to 60%,is extracted and pur-ified by various pyro- and hydrometallurgical methods. Ilmenite provides over 90 ...

Ilmenite – the primary source of titanium extraction by chlorine process . Ilmenite is the most important ore of titanium mining with the chemical formula FE-TI-O3 (iron, titanium and oxygen), named for its place of discovery at Ilmen Lake in the Ilmen Mountains, Miask in the southern portion of the Ural Mountains of Russia.
The multi-element solution prepared by dissolving ilmenite in concentrated sulphuric acid was composed of 22.64% (w/w) of titanium, 71.28% (w/w) of iron, and 6.08% (w/w) of other impurities determined by ICP-OES. After precipitating out titanium-tannic acid complex with tannic acid containing ammonium hydroxide at a pH of
Oxygen yield from lunar soils is strongly correlated with initial iron content (Figure 2). The dominant iron-bearing phases in lunar soil are ilmenite, olivine, pyroxene, and glass. Each of these phases is a source of oxygen. Ilmenite and iron-rich glass react most rapidly and completely. Olivine is less reactive.
"As part of a U.S. Bureau of Mines program to develop a more continuous titanium metal extraction process that uses domestic resources, a study was made to determine the extraction of titanium (Ti) and iron (Fe) from New York rock ilmenite using fluosilicic acid (H2SiF6 ).
Feb 27, 2018· Ilmenite is the most abundant oxide mineral found in Lunar rocks. This is good because it has a very useful composition (FeTiO 3). Ilmenite is also the principal ore for titanium on Earth. We can easily (relatively) extract iron, oxygen, and titanium dioxide from ilmenite. Abundance and distribution

of the ilmenite and lead a lower reduction degree.22) There-fore, it is considered that the lower reduction rate of Bama ilmenite is due to the manganese oxide contained as an im-purity. The silica would also inhibit the reduction due to the formation of fayalite during the reduction process which decreases the reactivity of the iron oxide.
Titanium compound is generally in combination with iron as ilmenite (FeTiO 3), which so-called iron-titanium sand3,4. Ilmenite contains nearly 53% of TiO 2 (rutile) and is an essential mineral for the processing of titanium with silica impurities of about 10%, iron oxide, vanadium, niobium, tantalum, tin, chromium, and molybdenum compounds.
