Ilmenite for pigment and metal production - OA Text
Rutile is easy to process to titanium metal or TiO2 pigment by the chlorination method while ilmenite is more compli ed because of its high iron content. Since the world reserves of titanium are 90% in the form of ilmenite and only 10% in the form of rutile, the treatment of ilmenite is evidently an important question in metallurgy 1,2 .
Towards sustainable TiO2 production: An investigation of ...
2018/09/20& 0183; Ilmenite is a titanium-oxide mineral which is upgraded to 85 to 95 percent titanium oxide which in turn comes as rutile. Synthetic rutile production consists of two stages including pyro-metallurgical processing, while ilmenite is heated in a large rotary kiln. It produces iron oxide impurities within the crystal lattice.Cited by: 17

Dec 02, 2016& 0183; Mechanically activated rutile ore used in aluminothermic reduction saved 30% booster expenses and decreased Cl2 emissions. Mechanical activation of ilmenite and ilmenite/aluminum mixtures was performed, and the kinetics of subsequent hydrometallurgical production of synthetic TiO2 by pressure and normal leaching were studied.
PRODUCTION OF RUTILE AND IRON FROM ILMENITE - …
In many prior art processes for producing rutile from ilmenite, the iron oxide in the ilmenite is selectively reduced to metallic iron, and the iron is then removed by converting it to iron oxide, ferrous salts, or ferric salts. Such processes are disclosed, e.g., in U. S. Pat. Nos. 3,112,178; 3,252,787 and 3,257,198.
Ilmenite - chemeurope.com
Distinguishing features . Ilmenite is often recognised in many altered igneous rocks which is most, to some extent by the production of the white pseudo-mineral leucoxene.Often, ilmenites are rimed in leucoxene, which allows ilmenite to be distinguished from magnetite and other iron-titanium oxides. The example shown in the image at right is typical of leucoxene-rimed ilmenite.
