摘　　要：对广西某含铁品位为52.07%、磁性率(FeO/TFe)为2.11%的难选赤褐铁矿矿石进行理化性能分析和矿物工艺学研究,并进行了强磁选、还原焙烧—磁选选矿试验,确定还原焙烧—磁选可以获得较好的选别指标为:精矿铁品位达63.27%,产率达82.70%,铁回收率95.99%,有害元素硫,磷都较低,SiO2、Al2O3、CaO、MgO的含量都能满足高炉冶炼的要求,属于优质铁精矿.Physicocheemical property, technique of mineralogy and test of mineral processing such as magnetic separation at high intensity and reducing roasting-magnetic separation were completed on the refractory hematite limonite of Guangxi with iron content about 52.07%, rate of magnetism（FeO/TFe） about 2. 11%. Tests of reducing roasting-magnetic separation could attain good results such as： concentrate iron grade are 63. 27%, productivity above 82. 70%, recovery of iron above 95. 99%, content of SiO2 ,Al2O3 ,CaO,MgO and deleterious composition such as S and P are as low as to be well fitted with demand of ironmaking in blast furnace. So the iron concentrate is a kind of product with high quality.
