An alternative approach to addressing the wastes discharge as well as obtaining high quality of titanium dioxide is to separate titanium and iron from the ilmenite sulfuric acid leachate prior to hydrolysis (Duyvesteyn et al., 2002). Solvent extraction is one of the most effective technologies for solution purification.

Table 3 provides the outputs of the ilmenite and rutile extraction process where the functional unit for both processes is 1 kg of mineral sand. It also shows the radioactive emissions associated with mining activities such as uranium ions, thorium ions and radium ions ( Navarro and Zhao, 2014, Norgate et al., 2007 ).

1. Introduction. Titanium dioxide, an important intermediate in the manufacture of paints, paper, inks, rubber, floor covering, ceramics, pharmaceuticals and other areas of chemical industry, is commercially manufactured by two main processes, namely the sulfate process and the dry chlorination process, .In the sulfate process, the ilmenite ore is dissolved in sulfuric acid solution ...

calcined for ±7 hours at temperature of 500 oC and 1000C to obtain TiO 2 anatase and rutile then purified with HCl and HNO 3. XRD and XRF characterization results showed the obtained TiO 2 extract containing anatase of 8.97% (70.3°; 1.337 Å) and rutile of 19.78% (54.2°; 1.699 Å).

In this study, TiO2 nanoparticles have been obtained from low-grade ilmenite ore via two consecutive acid digestion and solvent extraction processes. The as-extracted TiO2 (Anatase phase) product was characterized using techniques such as XRD, XRF, FESEM, FTIR and BET surface area. Diluted sulfuric acid and D2EHPA (bis-(2-ethyl-hexyl) phosphoric acid) were used as digester agent …

Extraction with hot 9 mol dm−3H2SO4 of the water-insoluble residue from the fusion of ilmenite with Li2O·6B2O3 yields a product containing 86 weight % TiO2 and only a trace of iron.

Iron oxide and titanium dioxide powders were produced on batch-basis from the pilot-scale hydrometallurgical strip solutions. A 98.5% pure Fe 2 O 3 powder was generated via precipitation and calcination. A crystalline rutile TiO 2 powder was produced via precipitation and calcination at a purity level of 99.3% TiO 2. The TiO 2

Ilmenite – the primary source of titanium extraction by chlorine process . Ilmenite is the most important ore of titanium mining with the chemical formula FE-TI-O3 (iron, titanium and oxygen), named for its place of discovery at Ilmen Lake in the Ilmen Mountains, Miask in the southern portion of the Ural Mountains of Russia.

Reduction of titanium by aluminum from ilmenite and rutile proceeds via the formation of intermediate monoxide TiO TiO x, which, as basic oxide, is able to form titanium aluminate. This decreases the activity of TiO and makes titanium recovery more difficult. Ver Precio extraction of titanium dioxide from ilmenite ore Mineral.

Ilmenite (FeTiO3) is a mineral that abundantly available in nature. Its extraction process can provide titanium dioxide (TiO2) which is useful for various strategic applications including dye-sensitized solar cells, photocatalysts, and water splitting. To obtain TiO2, ilmenite has to be converted first into titanium oxysulfate (TiOSO4) precursor.

An improved process is described for producing titanium dioxide from ilmenite-type ore. The ore is digested with aqueous hydrogen fluoride, the resulting liquid mixture treated with a water-soluble oxidizing agent, and the ferric iron impurities, in the resulting digestion solution, at a pH between about 1.0 and 6.0, are extracted out with a mono-or dialkyl, or mono- or di-(alkylphenyl ...

Solutions of ilmenite (FeTiO 3) and a titaniferous slag, in fused Li 2 O. 2B 2 O 3 and Li 2 O. 4B 2 O 3, yield on cooling compounds tentatively identified as LiFe 2. 5 Ti 3 O 9 and Li 2 Fe 3 Ti 2. 5 O 9 respectively. Both compounds are orthorhombic, and have the pseudobrookite structure. The ilmenite solutions yield, in addition, rutile (TiO 2).The yield of rutile increases from about 1 to 24% ...
