Becher process [10], Murso process [11-12], Laporte process [13], Benelite process [14] and Austpac process [15]. Most of the previous processes involve high temperature pretreatment of ilmenite, which is an energy consuming and most of the subsequent acid leaching requires pressurized conditions, which make the process more complicated.
