ABSTRACT:
A cyclic, ideally continuous, process for producing titanium which employs the reduction of titanium fluorides by potassium or sodium, or mixtures thereof, to result in titanium particles in molten alkali metal fluoride, which after separation said alkali metal fluoride is combined with a molten ferrous metal to evolve the alkali metal to be recycled from alkali metal iron fluoride that is then combined with a titanium dioxide containing mineral, ideally ilmenite, to evolve titanium tetrafluoride which is recycled. The process may be employed to produce other metals, especially aluminum, silicon and zirconium.
