Titanium is a metal which is resistant to corrosion and high temperatures, with a high melting point, and low weight. Titanium can be extracted by hydrometallurgy method which includes ilmenite leaching with hydrochloric acid and sulfuric acid13-15. This process is one of the effective separation method for separating minerals from other elements.
