Results from studies of the use of reverse cationic flotation and an effective new reagent-based method for the beneficiation of waste products (Fe ~25% and SiO2 ~54%) formed in processing iron quartzites from the Mihailovskii deposit show that the hematite concentrate which is obtained has an iron content of roughly 60% and contains less than 5% SiO2 (without preliminary dressing). The use of high-gradient magnetic separation for beneficiation of the same waste products yielded iron concentrate with excellent processing properties. It is found that a technology which combines magnetic separation and flotation is the most promising approach to the concentration of materials that contain hematite.
