摘　　要：根据某鲕状高磷赤铁矿的矿石性质,采用反浮选—焙烧—磁选流程,获得铁品位60.09%,铁回收率70.04%,含磷0.23%的铁精矿,有效地解决了鲕状赤铁矿含磷偏高的问题,可为我国开发高磷赤铁矿提供技术参考。According to the ore property of the oolitic high phosphorus hematite,the reverse flotation-roasting-magnetic separation technical process is adopted,and the iron concentrate with 60.09% iron grade,70.04% iron recovery 0.23% phosphorus is obtained.Thus the problem of too much phosphorus in the oolitic hematite can be effectively solved,thus providing a technical reference for exploiting high phosphorus hematite.
