| 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.

| Abstract: | 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, for the treatment of similar low-grade iron manganese ore has played a certain reference role. |
