摘　　要：采用擦洗磨矿—重选抛尾—精矿浮选—浮选精矿磁选和化工提纯的工艺,可获得金红石精矿产率1.50%,品位RTiO2为90.80%,金红石回收率62.13%的试验指标。A technology flowsheet with scrub-grinding-gravity concentration-flotation of the concentration of gravity-magnetic separation the concentration of flotation-hydrometallurgy was established. A exceed targets that the yield rutile concentration was 1.5%, the grade of RTiO_2 was 90.80% and the recovery of rutile was 62.13% were obtained.
