  • Patent number: 11473207
    Abstract: 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 Ti—C—S/titanium sulfide anode material with high electric conductivity through a sintering reaction, and then uses the Ti—C—S/titanium sulfide anode to prepare metallic titanium in a molten salt electrolyte system successfully. With the Ti—C—S composite soluble anode in the present invention, metallic titanium is deposited at the cathode and CS2/S2 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.
