内蒙古阿拉善额日登基性岩体中超低品位铁矿石特征及选矿工艺研究

Characteristics of low grade iron ore and beneficiation process for basic rock in Eri Teng,Alxa,Inner Mongolia

通过合适的选矿工艺,将超低品位铁矿石中的铁选出成为可利用的资源,为解决铁矿石资源紧张提供新的、广阔的来源.调查了内蒙古阿拉善地区基性岩中铁矿石铁的质量分数分布情况,并分析了额日登基性岩体磁性异常区中含铁辉长岩特征,对其中的超低品位铁矿石进行分选工艺试验,确定了可行的工艺流程.

By appropriate mineral processing technology,selecting ultra low-grade iron ore as available resources resolves the tension state of iron ore resources supply and provides a new,broad source.Iron mass fraction distribution in iron ore basic rock in Alxa region was surveyed,and the characteristics of iron gabbro was also analyzed where basic rock magnetism is abnormal in Eri Teng,a feasible process was confirmed by the separation process test for some of ultra-low-grade iron ore rock.
