摘　　要：针对某微细粒难选赤铁矿展开多种选矿工艺流程对比试验研究,研究结果表明,采用焙烧-磁选和强磁-焙烧-弱磁选流程可有效选别该矿石,均可获得合格铁精矿。Directed at the properties of a fine - grained and refractory hematite ore, comparison tests of multiple technological flowsheets were performed. The results showed that when the two kinds of technological flowsheets of roasting- magnetic separation or high intensity magnetic separation- roasting- low intensity magnetic separation are selected for separating this hematite ore, qualified iron concentrate can be obtained.
