摘要
目前，我国的铁矿山以露天开采为主，采出的矿石均需进行选矿加工。矿床的开发利用程度不高，矿石回收率很低，尤其对多组难选矿石的利用程度更低．为使我国铁矿开发利用更好地顺应自然发展，文中论述了除增加地质勘查费与采矿投资外，还应对表外矿、铁尾矿和多组分矿石的综合回收与利用。
At present, most of iron ore mines in China are open-pit ones. All mined iron ore must be pro-cessed by concentration. The levels of both ore exploiration and utilization arn't high; the ore recoveryis very lowl in particular the level of multi-compound refractory ore utilization is even lower. In orderto that China's iron ore development and utilization better accord with natural status, this paperPointes that apart from increasing investment to geological exploration and mining should consider thecomprehensive recovery and utilization of ore outside balance table, the iron tailings and multi-com-pound ore.
