摘要
采用预先分级、干式磁选抛废、粗磨磁选、粗精矿再磨再磁选的工艺流程处理大顶铁矿原生矿,提高了原矿处理量,降低了磨矿成本,获得铁精矿品位65.54%、铁回收率94.11%的技术指标.
The original mineral of Dading Iron Mine was processed by the technique which in- cluded pre-classification, dry magnetic separation to discard dirt, magnetic separation of the coarsely ground ore, scondary grinding and secondary magntic separation of the rougher con- centrate, thus raising the processing quantity of the crude ore, reducing the grinding cost, with the grade of iron concentrate 65.54%, the recovery of iron 94.11%.
