Abstract: A super pure iron concentrate containing TFe 72.02% and SiO2 0.27% was produced with a common iron concentrate containing TFe 67.70% and SiO2 4.88% by a process consisting of grinding, low magnetic separation-magnetic and gravity separation-reverse flotation, and at the same time, a common iron concentrate grading 70.57% iron was also produced, with the total iron recovery reaching 91.96%.

Key words: Super pure iron concentrate, Magnetic separation, Reverse flotation
