摘要
某铁矿原矿品位:MFe6%,TFe22%左右,属于贫磁铁矿。随着铁精粉价格走低,企业陷入亏损状态。通过做干式磁选试验后,在采矿场附近建成干式磁选厂,预选富集,抛除大部分合格废石。降低成本,企业扭亏为盈,年增效益800余万元,取得了较好的经济效益。
An iron ore grade：MFe6%, about TFe22%, belonging to poor magnetite. With iron ore falling, enterprise into a loss. After doing by dry magnetic separation test, built in the vicinity of the dry magnetic separation plant, pre-enrichment, in addition to waste rock throwing most qualified. Reduce costs, corporate profitability, annual benefit more than800 million, achieved good economic results.
