Ilmenite for Pigment and Metal Production.pdfInterdisciplinary Journal of Chemistry (2016)
Low-grade ilmenite can be leached with concentrated HCl at atmospheric pressure and at 80°C. After filtration to separate insoluble matter the solution containing TiO2+ and Fe2+ is heated to precipitate titanium hydroxide and recover HCl. The titanium hydroxide is then calcined to synthetic rutile containing 95+%TiO2 while FeCl2 is subjected to oxyhydrolysis or fluidized be to recover HCl and Fe2O3. The process naturally can be applied to high grade ilmenite. It bypasses electric furnace process which applies only to high grade ilmenite and is superior to the sulfuric acid process which is highly pollutant. The product of this process can be used to prepare the white pigment as well as titanium metal.
