Among them, the reverse flotation method of iron ore has low separation particle size lower limit and separation speed. Fast, easy to control and other advantages, which has been widely used in iron ore dressing plants. The reverse flotation process of iron ore is used in iron ore with complex iron mineral composition and high iron grade.
Research regarding iron ore flotation began in 1931, demonstrating that reverse cationic flotation is a very efficient method for beneficiating oxidised iron ores. This method can also be applied to reduce the silica content in magnetite concentrates obtained using wet lowintensity magnetic separation.
Since the early stage of technology development for iron ore ﬂotation in the 1930s, the following two technical routes of iron ore ﬂotation have been developed: (i) direct ﬂotation of iron oxides and (ii) reverse ﬂotation of gangue minerals by depressing iron oxides. The route of reverse ﬂotation is currently
