Provided is a method for preparing metallic titanium by anode-electrolysis of carbonized/sulfurized ilmenite, and relates to the technical field of mineral processing and electrochemical extraction of metallic titanium in molten salts in non-ferrous metallurgy. The method uses titanium-containing ore, carbon (C) and sulfur (S) as raw materials and prepares a TiCS/titanium sulfide anode material with high electric conductivity through a sintering reaction, and then uses the TiCS/titanium sulfide anode to prepare metallic titanium in a molten salt electrolyte system successfully. With the TiCS composite soluble anode in the present invention, metallic titanium is deposited at the cathode and CS.sub.2/S.sub.2 gas is generated at the anode in the molten salt electrolysis process; in addition, the gas can be used as a raw material to effectively treat the ore to prepare titanium sulfide.

Systems and methods for feeding solid material and a gas into a container (e.g., electrolytic cell) are generally described. Certain methods comprise feeding solid material and a gas into an electrolytic cell through an inlet; wherein: the gas comprises an inert gas; and the inlet is positioned, relative to an anode of the electrolytic cell, within a distance that is less than or equal to 5 times the shortest cross-sectional dimension of the anode. Certain systems comprise a container configured for molten salt electrolysis; a passageway configured for feeding solid material and a gas into the container; an anode; a cathode; and an outlet configured for releasing a gas from the container; wherein an inlet from the passageway to the container is positioned, relative to the anode, within a distance that is less than or equal to 5 times the shortest cross-sectional dimension of the anode.

The titanium-containing oxide slag, low-purity silicon and slagging fluxes are subject to reduction smelting together, and a bulk SiTi intermediate alloy is obtained by slag-metal separation; the obtained bulk SiTi intermediate alloy is crushed into SiTi intermediate alloy particles; and the obtained SiTi intermediate alloy particles are used as an anode, metallic molybdenum or metallic nickel as a cathode, metallic titanium as a reference electrode, and NaClKClNaF together with small amounts of Na.sub.3TiF.sub.6 or K.sub.3TiF.sub.6 as a molten salt, to carry out the electrolysis under a high-purity argon atmosphere at a temperature of 973 K. Ti in the SiTi intermediate alloy particles dissolved at the anode and deposited at the cathode, while Si in the SiTi intermediate alloy particles fell off from the anode as metallic silicon powder.

A process is disclosed for the electro-refinement of titanium aluminides to produce titanium-aluminum master alloys which process is effective even in the presence of substantial amounts of aluminum and in the presence of ten (10) or more weight percent oxygen in the material(s) to be refined. The process is likewise effective without the addition of titanium chlorides or other forms of soluble titanium to the electrolyte bath comprising halide salts of alkali metals or alkali-earth metals or a combination thereof.
