| Abstract: | For an iron ore, the iron minerals are finely disseminated, yet, the composition of gangue minerals is simple, among which SiO_2 accounting for 45.81% in content, is the main composition. When a high effective anionic collector showing high selectivity to SiO_2 was introduced and a process flowsheet of stage-grinding and whole reverse flotation was applied, an iron concentrate with a TFe grade of 65.50% and a recovery of 81.62% was obtained. |
