| Abstract: | An iron ore from Benxi in Liaoning Province with TFe grade of 30.45% was taken as the raw material to prepare super iron concentrate by adopting a process consisting of staged grinding-low intensity magnetic separation-magnetic column reducing silicon-reverse flotation. Finally, a super iron concentrate was obtained with TFe grade of 71.25%, TFe recovery of 65.02%, SiO2 content of 0.15% and acid-insoluble residue content of 0.10%, and a common iron concentrate was obtained with TFe grade and recovery of 65.28% and 19.64%, respectively. |
