摘要
云南怒江地区某低品位菱铁矿含TFe 25.67%,金属矿物主要为菱铁矿,还有少量黄铁矿、黄铜矿等,脉石矿物主要为石英,绢云母等,为有效开发利用该矿石资源,对有代表性的矿石进行了详细的试验研究,最终采用强磁选—焙烧的选矿工艺流程,获得了铁品位57.95%、回收率为80.13%的铁精矿,为同类型矿石的开发利用提供了借鉴。
A low grade siderite from Nujiang area contains 25. 67% TFe. The main metallic minerals were siderite with a little pyrite and chalcopyrite,and the gangue minerals were quartz and sericite. For effective exploration and utilization,experimental tests were conducted systematically and an iron concentrate containing 57. 95% TFe with recovery rate of 80. 13% was obtained using a high intensive magnetic separation- roasting process,which provides a reference for development of similar type ore.
