The beneficiation of Anshan-type low-grade hematite ores attracts more and more attention. Complicated beneficiation flow sheets are necessary to deal this type of ores. Classification-gravity concentration technology is used widely in these flow sheets because of its characteristics. In this paper, grinding characteristics and classification-gravity concentration tests were carried out based
