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 TiO2 into TiCl4. The ore rutile (impure titanium (IV) oxide) is heated with chlorine and coke at a temperature of about

Reduction with carbon normally involves heating the metal oxide in the presence of the carbon, which is often used in the form of coal. Most metals are only found as compounds because the metal has reacted with other elements in the past. Because of this, the metal has to be extracted from the ore (rock) where the metal compound is found.
