摘　　要：小型试验和半工业试验表明，将安庆铜矿生产中含ＴＦｅ６４．６８％、ＳｉＯ２４．６２％的普通铁精矿经旋流器分级、溢流磁选、磁精矿反浮选脱硅，可获得产率９．２３％、ＴＦｅ６９．０７％的高纯铁精矿和含ＴＦｅ６４．４８％的铁精矿。A reverse flotation process for a high purity iron concentrates have been conducted on pilot-scale in Anqing Copper Mine. 40% of conventional concentrates were directly fed to the process of hydro-cyclone classification overflows magnetic separation reverse flotation processing of magnetics. By such process and from the conventional concentrates of TFe64.68%, SiO24.62%, a high purity concentrate with TFe69.07%, yield 9.23% and an ordinary concentrate with TFe64.48% were produced.
