New processes to produce metallic titanium, aiming to be alternative for Kroll process, are currently developed by many innovators and researchers in the world. They are here classified depending upon the starting materials. New approaches starting from TiO2 (not via TiCl4) are tentatively studied in the calcium reduction, OS process, FFC process and some molten electrolysis at high temperatures. Their mechanisms for reduction and their features are summarized and discussed in the view of industrial application. The gaseous reactions starting from TiCl4 are also proposed using hydrogen, sodium or magnesium as the reductant. Their advantages are high reduction rate and continuous operation.
