摘　　要：本文针对云南某地锰品位13.88%、铁品位19.87%的贫锰铁矿石,在常规物理选矿方法分选效果不佳的情况下,采用干式抛尾-还原焙烧-弱磁选铁-选铁尾矿强磁选锰工艺处理该矿石。该流程最终获得铁品位53.89%、回收率65.53%的铁精矿和锰品位27.11%,锰回收率为70.26%锰精矿,为处理类似低品位铁锰矿石起到了一定的借鉴作用。In this paper,a kind of low-grade ferromanganese ore with mangane grade of 13.88% and iron grade of 19.87% in Yunnan province was used in the case of poor sorting effect of conventional physical beneficiation method.The ore was treated by dry magnetic tailing-reduction roasting-weak magnetic separation iron-iron tailings.The process finally obtained iron grade 53.89% ,recovery rate of 65.53% iron concentrate and manganese grade 27.11% ,manganese recovery rate of 70.26% manganese concentrate,which played a certain reference role for the treatment of similar low-grade iron manganese ores.
