The invention relates to a method for extracting scandium from artificial rutile leaching mother liquor produced by a hydrochloric acid method, belongs to the technical field of extraction of scandium, and aims to provide a high-extraction-rate method for extracting the scandium from the artificial rutile leaching mother liquor produced by the hydrochloric acid method. According to the method disclosed by the invention, a scandium solution is obtained by extraction from the artificial rutile leaching mother liquor produced by the hydrochloric acid method through the steps of extraction, pickling, reverse extraction, washing and the like via tributyl phosphate serving as an extraction agent, and the leaching mother liquor is recycled. The method is easy to operate, low in cost and high in extraction rate; the scandium solution is obtained by extraction contains less impurities and is favorable for subsequent preparation of metal scandium or scandium oxide.
