| 摘 要： | 对某磁铁矿进行工艺矿物学研究,查明该矿石全铁含量为54.90%,主要的磁性矿物为磁铁矿。针对该磁铁矿性质,制定了弱磁选流程方案。试验流程为一次弱磁选粗选和一次弱磁精选。试验研究结果表明,磨矿细度为-0.074mm占55.77%、弱磁选粗选和精选的磁场强度均为66mT时,可以获得品位64.53%、回收率87.99%的铁精矿,富集比为1.18,选矿比为1.41。

| Abstract: | Based on the mineralogy process study of the magnetite ore,proves that the content of Fe is 54.90%,and the main magnetic minerals are magnetite ore.For the magnetite ore character,developed the flow of low intensity magnetic separation.When the degree of grinding is 55.77%(-0.074mm) and the magnetic intensity is 66 mT,using the low intensity magnetic separation,obtained an iron concentrate with 87.99% recovery and an iron grade of 64.53%.The enrichment ratio is 1.18,and the concentration ratio is 1.41. |

| Keywords: | magnetite low intensity magnetic separation enrichment ratio concentration ratio |
