    Abstract: A method for producing titanium tetrachloride is provided, in which valuable materials such as unreacted titanium-containing raw material, carbon raw material and chlorine can be recovered from solid recovered material generated in chlorinating process of titanium-containing raw material, and titanium-containing raw material can be efficiently used. The treatment method of titanium-containing raw material includes the steps: separating and removing impurities selectively from the titanium-containing raw material as chlorides so as to obtain high titanium-containing raw material, producing titanium tetrachloride using the high titanium-containing raw material, and performing separating process of impurities from solid recovered material byproduced in the production of titanium tetrachloride, together with selective chlorinating treatment of the titanium-containing raw material. Thus, the high titanium-containing raw material can be produced while recovering chlorine and impure oxides.

    Abstract: A technique is provided in which valuable material is recovered from solid recovered material generated during chlorinating process of titanium-containing raw material, and in particular, in which chlorine gas and titanium-containing raw material can be efficiently separated and recovered from the solid recovered material. The method for production of titanium tetrachloride includes: a chlorinating process in which titanium-containing raw material, coke and chlorine are reacted, a recovering process in which chlorine gas, titanium oxide and coke are recovered by treating solid recovered material which is byproduced during the chlorinating process, and a reusing process in which these recovered material are reused as raw material for the chlorinating process.
