摘　　要：为了更好地利用菱铁矿资源,对云南某铁品位为40.84%的难选菱铁矿石进行了磁化焙烧-磁选工艺试验研究,在不添加还原剂的条件下,在焙烧温度800℃、焙烧时间60 min时得到焙烧矿,焙烧矿经磁选后获得了铁精矿产率61.25%、品位64.65%、回收率96.96%的指标。可为高效利用菱铁矿资源的工艺设计提供依据。For making full use of siderite resources, an experimental study was carried out for processing a kind of refractory siderite grading 40.84% Fe from Yunnan Province by adopting a process composed of magnetic roasting and magnetic separation. Without any reducing agent, the roasted ore that was obtained after roasting at 800 ℃ for 60 min was then subjected to a magnetic separation, resulted in an iron concentrate grading 64.65% Fe at 96.96% recovery, with a yield of 61.25%, which can be of reference in the design of processing technique for highly efficient utilization of siderite resources.
