A direct leaching method of ilmenite using chloride media has been developed by Lakshmanan et al (2010). The process involves leaching the ore between 65 and 80 °C in 20% HCl and 150–300 g/L MgCl 2. Iron impurities are removed from the leach solution by solvent extraction using TBP and recovered as iron oxides through pyrohydrolysis.
