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.
