摘要
本文针对国内低品位磁铁矿的选矿工艺特点,对国内多个预先抛废工艺的磁铁矿选矿厂的生产情况进行了分析研究,验证了在低品位磁铁矿选矿过程中,预先抛废具有降低选矿能耗和选矿比,减少精矿加工成本和尾矿处理等优势,对提高低品位磁铁矿矿山企业的经济效益具有现实意义。
According to the processing characteristics of the domestic low-grade magnetite,this paper an-alyzes and studies the production situation of many domestic magnetite concentrators with pre-separation and sorting process,and verifies that in the processing of low-grade magnetite,the pre-separation and sorting process has the advantages of reducing beneficiation energy consumption and beneficiation ratio,reducing concentrate processing cost and tailings treatment cost,and it is of practical significance for im-proving the economic benefits of low-grade magnetite enterprises.
