Synthesis and characterization of TiO2 from ilmenite by caustic .

process involves addition of NaOH with the ilmenite ore to give a mol ratio (NaOH/FeTiO3) of 4 : 1 at a temperature of 650ºC for 120 minutes. The result from the caustic fusion (frit) was then leached with water to remove any residual excess of NaOH after the fusion process, followed by acid leaching using H2SO4 solution.

Ilmenite - Wikipedia

At higher temperatures it has been demonstrated there is a complete solid solution between ilmenite and hematite. There is a miscibility gap at lower temperatures, resulting in a coexistence of these two minerals in rocks but no solid solution. This coexistence may result in exsolution lamellae in cooled ilmenites with more.

US4085190A - Production of rutile from ilmenite - Google Patents

The metallic iron is then leached from the TiO 2 residues by solution in ferric chloride solution. As taught in that patent, in order for the reduction to metallic iron be readily accomplished, it is preferred to initially convert, by oxidation, the ferrous iron in the ilmenite to ferric iron prior oxidation step. It is required by that process.

Tannic Acid Selectively Extracting Titanium from Ilmenite .

In the sulfate process, low grade ilmenite (FeTiO3) can be used as a feed stock which is treated by concentrated sulfuric acid (H2SO4). In the next step, impurities are precipitated by cooling down the sulfuric acid solution and titanium dioxide can be obtained by performing hydrolysis on titanyl sulfate (TiOSO4) at 95-110°C.

Production of synthetic rutile from ilmenite via anion-exchange .

This investigation identified that ion-exchange chromatography can efficiently remove iron from the leaching of ilmenite by HCl. The strong basic anionic-exchange resin IRA 410 Cl is capable of retaining the negatively charged iron chloro complex from 20% HCl leachate of ilmenite. Oxidative conversion of Fe2+ to Fe3+.
