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 .
