摘要: 以含TFe 67.70%,SiO2 4.88% 的普通铁精矿为原料,采用磨矿、弱磁选—磁重选—反浮选工艺,可生产出含TFe 72.02%,SiO2 0.27% 的超纯铁精矿,同时可获得TFe 品位70.57%的普通铁精矿,TFe 总回收率达91.96% 。

关键词: 超纯铁精矿, 磁选, 反浮选

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
