Titanium Dioxide (TiO2) Production and Manufacturing ...
Mar 15, 2010 · The ore, usually an ilmenite, is dissolved in sulphuric acid to form a mixture of sulphates. Any iron is removed from the solution so the colour of the final product is not spoiled. The titanyl sulphate is then hydrolysed in solution to give insoluble, hydrated titanium dioxide.
Extraction of Titanium
This involves using carbon but is not the final step in extraction of the metal. titanium dioxide + carbon + chlorine titanium(IV) chloride + carbon dioxide. TiO 2 (s) + C(s) + 2 Cl 2 (g) TiCl 4 (g) + CO 2 (g) Step 3. We cool down the products and titanium(IV) chloride condenses to a liquid.
Titanium Ore Processing and Beneficiation
Its chief demands are as the metal in alloys, with a significant consumption as a white pigment in the paint industry. The value of titanium in sponge form is presently worth $9 to $10 a pound; in plate and sheet is 2 to 3X that. Titanium Ore Extracting Flowsheet The flowsheet shown was developed for a mixed rutile and ilmenite […]

extraction of titanium
Titanium is extracted from its ore, rutile - TiO 2. It is first converted into titanium(IV) chloride, which is then reduced to titanium using either magnesium or sodium. Conversion of TiO 2 into TiCl 4 The ore rutile (impure titanium(IV) oxide) is heated with chlorine and coke at a temperature of about 1000°C.
Recovery of TiO2 from ilmenite-type ore using an ...
Sep 18, 1979 · 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 ...
Chloride process - Wikipedia
The chloride process is used to separate titanium from its ores. In this process, the feedstock is treated at 1000 °C with carbon and chlorine gas, giving titanium tetrachloride. Typical is the conversion starting from the ore ilmenite : 2 FeTiO 3 + 7 Cl 2 + 6 C → 2 TiCl 4 + 2 FeCl 3 + 6 CO
