摘　　要：西部铜业巴彦淖尔铁矿磁选铁精矿Fe品位较低、含硫高、铁矿物嵌布粒度较细、脉石矿物主要为含铁硅酸盐。试验选取新药剂MG为捕收剂,采用常温阴离子反浮选的工艺流程,试验研究达到了良好的分选指标,精矿TFe品位达68.55%,回收率达94.2%,SiO2含量从7.19%降到1.85%,S从0.49%降到0.22%,实现了提质降杂的目标。In the magnetite concentrate for Bayannur iron ore in Western Copper Corp. , iron grade is low, the dissemination size is fine, the sulfur is high and the main gangue mineral is silicate containing iron, the processing flowsheet of anion reverse flotation by new collector MG at room temperature was adopted. The experiment had obtained good separation indexes. The concentrate grade was reached TFe 68.55% with a recovery of 94.7%. The content of SiO2 was decreased from 7.19% to 1.85%, and the content of S decreased from 0.49% to 0.22%, which realized the target of iron - increasing and impurities - reduction.
