| 摘 要： | 羚羊铁矿石矿物组成非常复杂、嵌布粒度很细、铁矿物与脉石紧密共生,难以分选.对羚羊铁矿进行了选矿试验研究,结果表明,采用焙烧-磁选工艺处理羚羊铁矿,可获得铁品位60%以上,回收率70%以上的铁精矿,选别指标较以往有很大的提高,为羚羊铁矿的进一步研究和工业利用打下了基础.

| Abstract: | The mineral processing study had been completed on Lingyang iron ores which were refractory ores due to complex composition,fine disseminated size and symbiosis with gangue mineral.Results showed that an iron concentrate with grade of over 60% Fe and a recovery of over 70% were obtained using reduction magnetization roasting-magnetic separation technology to process Lingyang iron ores.The separation index improved greatly and laid the foundation for further research and industrial utilization of Lingyang ir... |
