There are two commercial processes for titanium dioxide (TiO 2) production: the sulphate process and the chloride process. The sulphate process is performed through hydrometallurgical route and uses ilmenite ores or low grade titanium slag (72–87% TiO Ilmenite an overview ScienceDirect Topics,In the sulfate process, ilmenite or slag is attacked with sulfuric acid to give soluble sulfates. Controlled hydrolysis of the titanyl sulfate leads to precipitation of a hydrous oxide which Preparation of synthetic rutile via selective sulfation of ,PDF This paper describes a novel, facile chemical pathway for preparing synthetic rutile from ilmenite.

Titanium is the ninth most abundant element in the Earth’s crust and it is present mainly in the form of ilmenite (40–80% TiO 2), rutile (~ 95% TiO 2), anatase (> 95% TiO 2), and leucoxene (> 65% TiO 2) [35,36,37,38].Major ilmenite deposits of the world are found in countries such as Australia (eastern and western coast), South Africa (Richards Titanium processing Extraction and refining Britannica,Extraction and refining TiCl 4. The production of titanium metal accounts for only 5 percent of annual titanium mineral consumption; the rest goes to the titanium pigment industry. Pigments are produced using either a sulfate process or a more environmentally acceptable carbochlorination process (described below) that converts TiO 2 into TiCl 4.The latter Titanium Slag Project Update LB Group LB Group,Reduced ilmenite is also used in the sulphate TiO 2 manufacturing process. The titanium slag project started in early 2013. Construction was completed in mid2014 and started to operate in September of the same year. Until March over 20,000 tonnes of qualified titanium slag has been produced, as well as 14,000 tonnes of reduced ilmenite.
