The invention relates to a method for comprehensive utilization of titanium concentrate. The method for comprehensive utilization of titanium concentrate comprises the steps that the titanium concentrate and a reducing agent are mixed and then placed in a reduction furnace so as to be subjected to a reduction reaction after being heated, and a reduced product is water-quenched and cooled after thereaction is completed, so that a mixture is obtained; the mixture is crushed, ground and magnetically separated, so that a magnetic product and a non-magnetic product are obtained; and the non-magnetic product is soaked in acid, so that a titanium-rich material and leachate are obtained, and the titanium-rich material is used for preparing TiCl4 through a fluidizing chlorination method; and the obtained magnetic product is used as a cooling agent used for extracting vanadium from vanadium-containing molten iron. According to the method for comprehensive utilization of the titanium concentrate, comprehensive utilization of the titanium concentrate is achieved through high-temperature reduction of the titanium concentrate, water-quenching and cooling, magnetic separation and acid soaking, the quality of the titanium-rich material is high, and the grade of TiO2 reaches 80% or over; and the process equipment is simple and easy to operate, emission of three wastes is avoided in the whole process, cleanliness and environmental friendliness are achieved, and the method has good economic benefits and good application prospects.
