中文摘要：

基于云南惠民铁矿主要为细粒浸染结构、氧化矿的主要铁矿物为褐铁矿,以氧化矿为研究对象,采用微波磁化焙烧-弱磁选工艺分选铁矿石,考查微波焙烧温度、还原剂用量、磁选磁场强度对分选指标的影响。研究结果表明：在焙烧温度为800℃,还原剂用量为12%,还原时间为12 min,磁选磁场强度为119.37 kA/cm的条件下,获得铁精矿品位为59.31%,回收率为81.92%,证实微波磁化焙烧铁矿石的方法可行,为难选铁矿石的分选提供了一种新的思路。

英文摘要：

Based on the fact that the iron ore in Yunnan Huimin is mainly fine-grained impregnation structure whose major iron ore of oxide ore is limonite,the oxide ore was studied,and the iron ore was sorted with the craft of magnetization roasting-low intensity magnetic separation.The effects of the microwave roasting temperature,and the amount of reducing agent,magnetic field strength on the index of separation were investigated.The results show that the preparation concentrate grade is 59.31% and recovery is 81.92% under the condition of roasting temperature of 800 ℃,amount of reducing agent of 12%,reduction time of 12 min and magnetic field strength of 119.37 kA/cm.It confirms that the method of microwave magnetizing roast of iron ore is feasible,which provides a new way for the difficult separation of iron ore.
