摘　　要：根据加拿大某磁铁矿的原矿性质,进行了脱除磁黄铁矿浮选试验研究。采用硫酸+硫酸铜作为活化剂,异戊黄药+丁铵黑药作为捕收剂,BK204作为起泡剂,可以实现磁铁矿与磁黄铁矿的分离。实验室闭路浮选试验获得铁精矿铁品位67.51%,铁回收率92.69%,铁精矿硫品位0.16%,硫脱除率94.72%的选别指标。According to the properties of a magnetite ore from Canada, experimental study on desulphurization by flotation had been conducted. The pyrrhotite was successfully separated from magnetite with sulphuric acid and cu- pric sulfate as activators, isoamyl xanthate and ammonium butyl as collectors, BK204 as a frother. A closed-circuit flotation test was conducted on the basis of conditional experiments and open-circuit flotation experiments, with which an iron concentrate of 67.51% Fe and 0. 16% S with a＇ Fe recovery of 92.69% and a Desulphurization rate of 94. 72% was obtained.
