The peak intensity for ilmenite reduces as temperature increases; there are phase changes as the overlap between sulfur, TiO 2, and ilmenite observed when leaching was conducted at 45 °C. At 90 °C, a precise observation of the dominant TiO 2 phase constitution confirms the assertion that the pre-oxidized ilmenite leached successfully in the presence of ammonium.

Titanium Dioxide Production by Hydrochloric Acid Leaching ...

C. Leaching Leaching of roasted ilmenite products were carried out by hydrochloric acid solution at various concentrations. In the case of original ilmenite, the main iron cations are in the ferrous form, which are easier to dissolve, they have to migrate to the surface to be leached. In addition, it has been reported that dissolution of ilmenite follows the reaction specified by [8]:

Rutile may be separated from ilmenite or ilmenite ores by agitating a mixture of ilmenite and rutile in particle form in an aqueous solution containing a collection agent to which hydrogen peroxide has been added. The slurry in agitated form is treated with air to produce a froth. The ilmenite particles will attach themselves to the air bubbles in the froth and may be skimmed

Up-grading of natural ilmenite ore by combining oxidation ...

10.12.2017  Rutile (TiO 2 ) 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.
