Abstract: A technique is provided, in which impure metal is efficiently separated and removed from titanium-containing raw material such as titanium slag or ilmenite and high titanium-containing raw material is produced. The method for improving quality of titanium-containing raw material containing slag, including steps of: oxidizing the titanium-containing raw material, selectively chlorinating impurities in the titanium-containing raw material, and separating and removing the impure chlorides to obtain high titanium-containing raw material. Alternatively, in this method, the oxidizing treatment and the selective chlorinating treatment are performed simultaneously.

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.
