摘　　要：试验矿样取自云南铁矿选厂生产的铁精矿,原矿Fe品位44.96%,SiO2品位12.33%。在研究了该矿石化学成分与矿物组成的基础上,进行了反浮选脉石、从而提高铁品位的试验研究,最终得到Fe的品位51.11%、回收率达到89.12%的铁精矿,其中SiO2含量降到3.29%。从本文的结论可以知道,褐铁矿的反浮选工艺相对简单,关键在于反浮选脱硅的捕收剂。The ore sample is taken from the iron ore concentrate produced by an iron ore coneentration plant in Yunnan, the Fe content of raw ore is 44. 96% and the SiO2 content is 12. 33%. The reverse flotation of gangue is done and the iron grade of the concentrate is improved, which finally reaches to 51.11% Fe, the recovery of iron concentrate reaches to 89. 12% , and the SiO2 content drops to 3.29%. The reverse flotation technology for limonite ore is very simple from the conclusion, and the key is the collector for desilicication of reverse flotation.
