摘要/Abstract

摘要： 白云鄂博氧化矿石深度还原物料的矿物组成复杂、金属铁粒度较粗、残碳含量高，先采用磁重联合工艺流程预先脱碳，再经阶段磨矿—粗细分选流程选铁，可获得全铁品位为92.02%，金属化率为94.18%，铁回收率为93.27%的铁粉，该铁粉可作为炼钢的原料；尾矿中稀土品位15.10%，回收率97.18%，可作为分选稀土的原料。

Abstract: After the hematite ore from Bayan Obo was deoxidized, the samples were of complex mineral composition, course metallic iron grain and high content of residual carbon. Iron powder with a TFe grade 92.02%, a metallization rate 94.18% at an iron recovery 93.27% was obtained after combined flow sheet of magneticgravity separation followed by stage grinding-respective treatment of course and fine fractions. This powder can be used as steelmaking material. The tailings with a grade of rare earth 15.10% at a recovery 97.18% can used as material for beneficiation of rare earth.

Key words: Hematite ore from Bayan Obo, Deoxidized samples, Metallic iron grain, Magnetic-Gravity separation
