Production of Titanium

Titanium is primarily extracted from the mineral ilmenite, a titanium-iron oxide. The Kroll process, developed in the 1940s, is the most common method for producing titanium.

Step-by-Step Production Process:

1. Reduction of ilmenite to titanium tetrachloride (TiCl₄)
2. Purification of TiCl₄ through fractional distillation
3. Conversion of TiCl₄ to titanium sponge using magnesium
4. Melting and refining of titanium sponge to produce titanium ingots
