  • Patent number: 10081874
    Abstract: The present invention provides a method for electrowinning a titanium metal from a titanium-containing soluble anode molten salt, and relate to the technical field of nonferrous metallurgy. The method comprises: mixing a titanium-containing material and a carbon-containing reducing agent at a mol ratio of 5:1-1:20 as a raw material, press-molding after uniformly mixing, holding a temperature range of 1000° C.-2000° C. under a nitrogen-containing atmosphere, reacting for 30-600 min; preparing a titanium-containing compound with a good electrical conductivity; and then electrowinning a titanium metal in a halide molten salt of an alkali metal or alkaline earth metal by using such a titanium-containing compound as an anode. The method for electrowinning a titanium metal from a titanium-containing soluble anode molten salt, provided by the present invention, is a simple in process and low in energy consumption, and can realize industrialized preparation of a high-purity titanium metal.
