Abstract: A method for preparing titanium metal by molten salt electrolysis is provided. The method includes constructing an electrochemical system, where an anode chamber is filled with an anode molten salt electrolyte that contains a titanium-containing raw material and inserted with an anode, a cathode chamber is filled with a cathode molten salt electrolyte and inserted with a cathode, and the anode molten salt electrolyte and the cathode molten salt electrolyte are not in contact with each other, but are connected by a liquid alloy at the bottom of the electrolytic cell; the system for electrolysis is powered on to obtain the titanium metal product at the cathode. The method of the present disclosure can treat low-quality titanium-containing materials, can be operated continuously, and can obtain relatively high-quality titanium.
