Titanium, the ninth most abundant element, occurs mainly in minable form as ilmenite (95%) and rutile (5%) minerals. The current world consumption of these minerals is used mainly to produce titanium dioxide pigments, with the balance in welding rod flux and titanium metal. Ilmenite is currently being mined in annual quantities eight times larger than rutile. In the past 35 years, …
Alkali roasting of the ilmenite process, which is a pre-treatment of the hydrometallurgical process for obtaining high titanium yields, has been studied by several groups 22,23,24,25.
Rutile (TiO2) is heavily used in pigments and colorants, and the most abundant source of rutile is ilmenite. Upon oxidation of ilmenite, rutile can be formed with modest energy consumption; furthermore, after leaching, only a few byproducts are formed. Unfortunately, one drawback is the necessarily long oxidative process of typically used methods. In this study, …
This research focused on investigating the properties and phase transition of ilmenite ore with various carbon reductants by performing a carbothermal reduction, followed by a hydrogen reduction (Ar:H2) at 900–1000 °C to extract rutile from the ore. To comprehend the impact of the carbon structure and characteristics on the reduction performance and …
Rutile and ilmenite originally grew as crystals in igneous rocks such as granite, pegmatite and basalt and some metamorphic rocks. Over millions of years, these rocks were weathered and eroded forming small grains of quartz and other minerals including rutile and ilmenite. ... In the Becher process, ilmenite concentrate containing 55%-65% TiO 2 ...
The life-cycle impact-analysis results of ilmenite and rutile processing routes and the corresponding sensitivity analysis based on electricity grid mix shows that a significant …
High-quality ilmenite, leucoxene, and rutile can be directly used as feedstock for the production of TiO 2 pigments and titanium metal (Gázquez et al., 2014, Perks and Mudd, 2019). However, lower quality ilmenite requires prior processing to produce titanium slag or synthetic rutile (Perks and Mudd, 2019). Consequently, rutile is the most ...
The ratio of ilmenite to rutile in India is 10:1 (Babu et al. 1994). Ilmenite has the general formula FeO.TiO 2 but it also contains Al 2 O 3, SiO 2, ... An improved carbothermic reduction process to ilmenite ore is developed by use of charcoal-sodium carbonate-Jhamma Coal. Flux has been used to liberate Fe oxide enabling reduction to metallic ...
Another important parameter for the processing of ilmenite is the agitating speed. When the agitating speed is increased from 100 to 500 rpm in 100 rpm increments, the …

Titanium is not free in nature and must be extracted by several processes. The titanium ores that are mined are ilmenite [mixed oxide of titanium and iron (FeTiO 3 or FeO·TiO 2)], rutile, anatase, and brookite, which have the same formula (titanium dioxide TiO 2) and different crystalline structures.Other less common titanium oxide-bearing minerals are …
Because in ilmenite and rutile processing, minerals consumes huge amount of electricity to be produced, this has enormous effects on sustainability.
