  • 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.

  • Patent number: 11180863
    Abstract: A device and a method for preparing pure titanium by electrolysis-chlorination-electrolysis, wherein the device includes a first electrolytic cell, a second electrolytic cell, a chlorination reactor and guide tubes. The Cl2 generated at the anode of the first electrolytic cell is introduced into a chlorination reactor containing the TiCxOy or TiCxOyNz raw materials via a guide tube, and a chlorination is carried out to generate TiCl4 gas at a temperature of 200° C.-600° C. The TiCl4 gas passes through a guide tube into a cathode of the second electrolytic cell, and then an electrolysis is performed to obtain the high-purity titanium in the second electrolytic cell. At the same time, the Cl2 generated at the anode of the second electrolytic cell is recycled into the chlorination reactor in the first electrolytic cell to continue to participate in the chlorination of TiCxOy or TiCxOyNz.
