With using the red mud of Bayer process and industrial hydrochloric acid as main initial materials, iron oxide red was prepared by chemical precipitation technique. The character of the sample were characterized and analyzed by means of XRD, SEM, particle size analyzer, and chemical analysis methods, respectively. The optimal experimental condition of extraction of iron from red mud was obtained, and the key quality indicators of sample was conformed the requirements of iron oxide red by a variety of test and characterization.
