"At present we obtain 40,000 tons of ilmenite each year. This fetches $240 per ton on the international market. At present approximately 40,000 tons ilmenite, 25000 tons rutile and 1200 tons zircon are produced," said Mr. Gnaneswaran, the Acting General Manager of the Pulmoddai Ilmenite Factory, who has been in service there for 30 years.
Port Roper. Roper River Ilmenite Project. Our Roper River Ilmenite Project is located in the Northern Territory of Australia, 550 km to the southeast of Darwin and 120 km to the east of Mataranka. Our project occupies a large footprint in the region across Roper Highway and Central Arnhem Road. This area also bears the Roper Valley iron ore mine.
In the industrial production of TiO2, the sulphate process and chloride process are the two common methods utilized for extracting TiO2 from ilmenite and rutile, respectively. 2.1. Sulphate Process.

Previously, various particle size parameters (mean size, standard deviation, …
Ilmenite (Fe TiO 3, also known as Iron titanate, or iron titanium oxide) is a naturally occurring titanium and iron ore. It is named for the location where it was discovered, Ilmen Lake in the Ural Mountains of Russia. Ilmenite is currently the most important ore of Titanium for terrestrial production. It is reasonably abundant on Luna, the ...
ilmenite. ilmenite ĭlˈmĕnīt [ key], black mineral, iron titanium oxide, FeTiO 3, crystallizing in the hexagonal system. It is sometimes found as tabular hexagonal crystals but occurs more commonly as small grains in igneous and metamorphic rocks and in sands derived from them. Ilmenite has been noted as an important constituent of lunar rocks.

Ilmenite is a black colored heavy ore of iron and titanium. It is closely related to rutile. Material of up to 15% iron and other contaminants (and therefore 85% titanium) is called rutile whereas material of over 15% is called ilmenite (in …
A ilmenita (no Brasil) ou ilmenite (em Portugal) é um óxido natural de ferro e titânio (FeTiO 3 ). É um mineral de magnetismo fraco encontrado em rochas metamórficas e intrusões geológicas de rochas ígneas, especialmente gabros e noritos. Deve o seu nome ao local onde foi dberta, os Montes Ilmenski, perto de Miass, Rússia .
Ilmenite and Rutile are minerals classified as heavy minerals. They are integral components of beach sand deposits found along the coastal stretches of India. Ilmenite is represented chemically as FeO.TiO2 and rutile as TiO2. Both these minerals are rich in Titanium. Titanium dioxide (TiO2) is the key component in these minerals.
Ilmenite is the titanium-iron oxide mineral with the idealized formula FeTiO 3. It is a weakly magnetic black or steel-gray solid. From the commercial perspective, ilmenite is the most important ore of titanium. Structure and properties. Ilmenite crystallizes in the trigonal system.
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 …

Electron microprobe analysis showed enrichment in TiO2, MnO, and Cr2O3 contents in the altered products, while there was a loss of FeO and MgO in the grains during weathering. Ilmenite concentrates have TiO 2 contents (54 % wt %) consistent with a mineral group dominated by primary ilmenite and hydrated ilmenite in greater …
Description: Ilmenite supplies Fe2O3 and TiO2. A natural source of titanium and iron, available in either powdered or granular form. Powdered ilmenite may be used as a colorant in glazes, and to seed crystals in titania glazes. Granular ilmenite is sometimes used in small amounts (<1%) to color/speckle clay bodies.
