When dealing with the iron ore from a South African mine with a grade of % Fe and % SiO 2,the magnetic separation process could generate only a blast furnace grade pellet feed with the Fe grade <65% and SiO 2 content >6%. However, a iron concentrate with a grade of >69% Fe and SiO 2 content <2% could be obtained by reverse flotation. The result shown that the reverse flotation ...
