The invention belongs to the field of metallurgy and chemical industry, and particularly relates to a method for solving artificial rutile refinement. The invention aims to solve the technical problemthat the granularity refinement is very seriously thinned when adopting strong agitation leaching in the existing artificial rutile preparation process. The method for solving artificial rutile refinement comprises the following steps of (1) drying and sieving the titanium concentrate; (2) performing low-temperature weak oxidation reaction on the titanium concentrate at 800-850 DEG C; (3) then performing weak reduction reaction at 750-800 DEG C; (4) adding hydrochloric acid, and leaching under heating and stirring conditions; and (5) performing solid-liquid separation, washing and drying to obtain a titanium-rich material finished product. Through the method disclosed by the invention, the high-quality artificial rutile products meeting the requirements of boiling chlorination can be prepared, and the process flo
