在库尔斯克磁力异常区铁矿床开发过程中,每年开采了大量的氧化含铁石英岩并将其堆积成废石场。采用相应的处理工艺处理这种氧化含铁石英岩,可成为从中制取铁精矿的一种潜在资源。米海洛夫采选联合企业开采了含铁品位达65%(平均品位53%)的富矿石,不经选别就可用于烧结。1973年该企业开采和选别非氧化磁铁石英岩的第一批设备已投产。到目前为止,尚未开发的氧化含铁石英岩约占矿石总产量三分之一。
During the development of the Kursk magnetic anomaly area iron ore deposits, a large amount of oxidized iron-bearing quartzite is mined every year and deposited into a waste rock field. Using the appropriate treatment process to deal with this oxidized ferrous quartzite can become a potential resource for producing iron concentrates. Mining and mining Mihailov joint mining company with 65% iron grade (average grade 53%) of the ore, can be used for sintering without selection. In 1973, the first batch of equipment for mining and sorting non-oxidized magnetite quartzite was put into operation. So far, undeveloped oxidized ferrous quartzite accounts for about one third of the total ore production.
