摘　　要：对甘肃某矿山极贫铁矿石进行了矿石性质及矿石预选、磁选工艺等研究,确定了矿石的适宜选矿工艺,推荐了选矿工艺流程,最终获得了精矿品位65.36%、铁回收率63.49%的选别指标,为该矿石的开发利用提供了依据。Properties of an ultralow-grade magnetite ore were studied and tests on preconcentration and magnetic separation were carried out, and a suitable processing technique was determined. With the proposed mineral processing flowsheet, concentrate with the iron grade and recovery of 65.36% and 63.49% , respectively, can be prepared, and this study provides a basis for the exploitation of this kind of ore.
