摘要
对某含铁品位为24.05%、磁性率(FeO/TFe)为0.6%的难选赤褐铁矿矿石进行了选矿试验研究。考查了该矿石的矿物工艺学和磨矿特性,重点研究了还原焙烧-磁选分选情况。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58%以上,铁回收率60%以上。
In this paper, tests of mineral processing were finished on the refractory hematite limonite of Shanxi with iron content about 24.05%, rate of magnetism （FeO/ TFe） about 0.6%. Grindability and tech-nique of mineralogy of this iron ore were described. The major study was put attention on efficiency of magnetic separation at high intensity and reducing roasting-magnetic separation. Tests of reducing roastingmagnetic separation could attained good results as.. concentrate iron grade be about to 58%, recovery of iron above 60%.
