摘要： A method for the production of titanium trifluoride from a titanium-containing material, includes the steps of producing a fluoride solution of Ti(IV) from the titanium-containing material and reducing the Ti(IV) in the solution with a transition metal or an alloy of the transition metal. The transition metal is selected from manganese, iron, cobalt, nickel and zinc. An ammonium containing salt and either ammonia or ammonium fluoride are added to the resulting solution containing Ti(III) to produce a precipitate, and the precipitate is pyrolysed to produce titanium trifluoride.

摘要： A method of producing titanium metal from a titanium-containing material includes the steps of producing a solution of M'TiF6 from the titanium-containing material, selectively precipitating M'2TiF6 from the solution by the addition of (M')aXb and using the selectively precipitated M'2TiF6 to produce titanium. M' is a cation of the type which forms a hexafluorotitanate, M' is selected from ammonium and the alkali metal cations, X is an anion selected from halide, sulphate, nitrite, acetate and nitrate and a and b are 1 or 2.
