Abstract: A comprehensive utilization method for iron separation tailings from magnetizing-roasted red mud includes the following steps: performing a wet magnetic separation for tailing discarding on iron separation tailings from magnetizing-roasted red mud, to obtain a rough concentrate and non-magnetic minerals; performing a purification by gravity separation on the rough concentrate to obtain a wet iron concentrate and light minerals; dehydrating the wet iron concentrate to obtain an iron concentrate; combining, and then dehydrating, drying, and disintegrating the non-magnetic minerals and the light minerals, to obtain iron extraction tailings; uniformly mixing the iron extraction tailings, and crushed, ground, and dried limestone, clay, and quartz sand separation tailings according to a predetermined ratio to obtain a cement raw meal; pressing, and then calcining and quenching the cement raw meal to obtain a cement clinker; and mixing the cement clinker and a gypsum followed by a dry grinding to obtain a silicate c
