ABSTRACT:
Titanium tetrachloride is reduced at atmospheric pressure and 1245.degree.C to 1750.degree.C by molten manganese to give substantially pure molten titanium metal and gaseous manganese chloride. A counter-current stream of gaseous titanium tetrachloride contacts molten manganese to make the chlorine interchange. Titanium alloys with other metals which will not reduce titanium tetrachloride are made by adding such metals to the reactor with the molten manganese; and they end up as part of the melt with titanium. The manganese chloride formed is oxidized to the oxide while giving chlorine gas, to be used in forming the titanium tetrachloride; and the manganese oxide is carbo-thermally reduced by conventional methods to manganese metal for recycle.
