Titanium extraction. The overall process. 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.
الحصول على السعرTitanium occurs in more than 70 minerals, but only ilmenite and rutile are used for extraction of titanium dioxide and subsequent extraction of titanium metal. Due to decrease in rutile deposit, ilmenite is used as the alternative source of titanium dioxide. Ilmenite exists as a low
الحصول على السعرTitanium is obtained from various ores that occur naturally on the earth. The primary ores used for titanium production include ilmenite, leucoxene, and rutile. Other notable sources include anatase, perovskite, and sphene. Ilmenite and leucoxene are titaniferous ores. Ilmenite (FeTiO3) contains approximately 53% titanium dioxide.
الحصول على السعرIlmenite can also be improved and purified to Rutile using the Becher process. Ilmenite ores can also be converted to liquid iron and a titanium rich slag using a smelting process. Ilmenite ore is used as a flux by steelmakers to line blast furnace hearth refractory.
