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.
Ilmenite can be converted into pigment grade titanium dioxide via either the sulfate process or the chloride process. Ilmenite can also be improved and purified to rutile using the Becher process. Ilmenite ores can also be converted to liquid iron and a titanium-rich slag using a smelting process.
The DuPont Chloride [7,8] - Ilmenite process used a reducing atmosphere with chlorine to remove the iron content of the ilmenite, then the operating point is adjusted to chlorinate the balance of the mineral to TiCl 4. The carbochlorination reaction does not require that carbon be in direct contact with the ore.
The ilmenite mining process includes gravity separation, magnetic separation and electric separation. Firstly, the materials should be extracted from the mine. After this step, the concentrated mines which contain the gravity materials will get. You can get the ilmenite with the help of middle strong magnetic separation.
The agglomeration flotation of ilmenite refers to the technology that makes ilmenite hydrophobic by means of a collector adsorbed on the surface of ilmenite, and then makes the ore particles cluster by means of the capillary gravity of the bridge solution, and then carries out the separation after floating on it.
Most ilmenite forms during the slow cooling of magma chambers and is concentrated through the process of magmatic segregation. A large underground magma chamber can take centuries to cool. As it cools, crystals of ilmenite will begin forming at a specific temperature.
The historic difficulty in processing titanium resources from the OUI resulted from impurities, such as magnesium oxide, in the crude ore and concentrate products. Previous research found that a large portion of the magnesium is associated with the chemical composition of the ilmenite and cannot be removed using conventional processing techniques.
