摘　　要：含硫量是评价磁铁矿质量的重要标准之一,高硫磁铁矿脱硫长期以来是钢铁行业面临的一大技术难题。浮选是脱除磁铁矿中硫的主要途径,主要针对磁黄铁矿进行分析,由于其易氧化和被抑制,在浮选过程中必须进行活化,因此活化剂和活化机理研究是高硫磁铁矿浮选脱硫的重要基础。通过介绍了高硫磁铁矿浮选脱硫工艺研究现状,并总结了浮选脱硫机理的研究现状和进展,展望了浮选脱硫工艺的发展方向。Sulfur content is one of the important criterions to evaluate the quality of magnetite. How- ever, it has always been a technical problem to remove sulfur from magnetite in the iron and steel industry. Flotation is an effective way to remove pyrrhotite from magnetite. However, pyrrhotite is easily oxidized, which has a detrimental effect on the flotation of pyrrhotite. So activation of pyrrho- tite is an essential method for a good flotation result. Therefore, research on activator and activating mechanism is an important basis for flotation desulfurization. The paper mainly introduces the re- search status of magnetite flotation desulfurization process and summarizes the research progress on the mechanism.
