Titanium metal is mainly produced by reducing titanium tetrachloride (TiCl 4) which is manufactured from natural rutile or from ilmenite, called Kroll's process. Iron is separated from the ilmenite during a smelting operation, and a TiO 2-rich slag is produced which is then transformed to TiCl 4 by chlorination.
