奥列湼哥尔斯克(Оленегорск)选矿厂磁选的非磁性产品,由于其中含有大量的以赤铁矿存在的铁(15-20%),包括水力旋流器脱水,继而用跳汰机和摇床选别的流程予以选别.此时得到含铁61%的商品精矿和送去磨矿的中矿,水力旋流器溢流、跳汰机和摇床的尾矿都作为废弃尾矿.从磁选粗选尾矿中回收到商品精矿中的铁的回收率不超过40%,这是由于跳汰机从细级别(-0.2毫米)中回收铁的氧化物不令人满意的结果.
Magnetically-selected, non-magnetic products from the Oreyno-Gorgors concentrator, due to the large amount of iron present in the hematite (15-20%), including hydrocyclone dewatering and subsequent use of jiggers and Shaker choose other processes to be selected.At this time, 61% of iron ore concentrate and ore to be sent to the mine, hydrocyclone overflow, jig and shaker tailings are used as abandoned tail The recovery of iron from commercial concentrates recovered from magnetic separation of rougher tailings did not exceed 40% because of the unsatisfactory recovery of iron oxide from the jig (-0.2 mm) by the jig the result of.
