| 摘 要： | 吉林临江羚羊铁矿石含赤铁矿、磁铁矿、褐铁矿和菱铁矿等含铁矿物，铁矿物组成和构造极为复杂，脉石矿物鲕绿泥石极易泥化，故该矿石是一种极为难选的铁矿石。通过对该矿石进行焙烧-磁选试验表明，在适宜的条件下，焙烧-磁选可以使精矿品位最高达到60.83%，尾矿品位27.60%，精矿回收率64.10%。该试验研究为吉林临江羚羊铁矿石的利用奠定了基础。

| Abstract: | Lingyang iron ore of Jilin linjiang contains the hematite,magnetite,limonite and siderite,which has a complex Fe composition and structure.And the gangue mineral as chamosite was easy to be slimed.So this kind of ore is a refractory one.The experiments of roasting-magnetic separation for the iron ore showed that at a suitable condition,the Fe concentrate reached up to 60.83% at an iron recovery of 64.1% and Fe grade in tailing of 27.60% by the roasting-magnetic separation,thus laying a foundation for application of Lingyang iron ore in Jilin Linjiang. |
