Answer

Titanium is mostly found in the form of $TiO_{2}$ (rutile) and is extracted from its ore in a two step process. First, $TiO_{2}$ is converted to $TiCl_{4}$ as follows: $TiO_{2}(s) + C(s) + 2 Cl_{2}(g) → TiCl_{4}(l) + CO_{2}(g)$ In the next step, $TiCl_{4}$ is educed to Titanium using Mg or Na: $TiCl_{4}(l) + 2 Mg(l) → Ti(s) + 2 MgCl_{2}(l)$
