The extracted ilmenite and rutile are processed to obtain titanium dioxide (TiO2), which is then further refined to produce metallic titanium. Therefore, ilmenite and rutile, found abundantly in certain coastal tracts of India, are valuable sources of titanium.

Titanium ores are Sierra Leone's second largest export after diamonds and play an important part in the country's recovery in the wake of its civil war. The ore ilmenite is much more abundant than rutile. It is formed in magma chambers in intrusive rocks like nortite, anothosite and gabbro. Ilmenite solidifies at a much lower temperature ...

The flotation processing characteristics of pervoskite, ilmenite and rutile from igneous and sedimentary ores were examined in the course of developing a commercial treatment process. Flotability of these minerals was found to be strongly influenced by a) flotation pH, b) pulp treatment before flotation, and c) type of collector.

It was found that ilmenite ore mainly contained titanomagnetite, hematite, and titanium dioxide phases. After carbothermal reduction, the titanomagnetite phase from ilmenite ore was transformed into titanium dioxide, iron titania, iron, and titanium carbide at the highest reduction temperature (1400 °C) via XRD analysis.

TiO2 production is a key part of Ti metallurgy and Ti recycling, and the process itself has turned out to be energy-consuming and material-consuming. New technologies are needed to utilize complex Ti ores, such as ilmenite, and reduce the carbon footprint of TiO2 extraction. Ammonium sulfate roasting has been revealed as an …

Abstract In the south of the Far East of Russia, a new source of critically important metals (titanium and iron) has been discovered—ilmenite-titanomagnetite ores of mafic-ultrabasic rocks of the Sikhote-Alin orogenic belt. The results of studying the opening of the ilmenite-titanomagnetite ores of the ultrabasic rocks occurring in the …
