METHODS OF PRODUCING METALLIC TITANIUM, MANUFACTURING METALLIC TITANIUM DUST, PREPARING A TITANIUM ARTIFACT AND RECOVERING TITANIUM, AND TITANIUM DUST. A method for producing metallic titanium from a titanium-containing material that includes the steps of producing a M "TiF6 solution from a titanium-containing material, selectively precipitating M'2TiF6 from the solution by the addition of (M ') aXb is described. and use selectively precipitated M'2TiF6 to produce titanium. M "is a hexafluortitanate-type cation, M 'is selected from ammonium and alkali metal cations, X is an anion selected from halide, sulfate, nitride, acetate and nitrate eaeb are 1 or 2.
