| 摘 要： | 本文调查了河北省15座大中型铁矿山，系统地研究了河北地区铁矿资源的空间集聚特征和开发利用现状，具体分析了典型铁矿聚集区铁矿资源禀赋条件、开采和选矿的相似性和异质性、共伴生元素和尾矿的综合利用潜力，并给出了差异化利用的建议。研究结果表明:河北北部成矿类型是岩浆型铁矿床，河北东部成矿类型是沉积变质型铁矿床，河北中南部成矿类型是矽卡岩型铁矿床；三种类型的铁矿床中铁的品位和磁铁矿的占比呈现出矽卡岩型铁矿床＞沉积变质型铁矿床＞岩浆型铁矿床的规律，选矿回收率也呈现出同样的规律。岩浆型铁矿中的伴生元素TiO2，P2O5和Sc，具有回收利用的价值，应该加强综合利用的研究。铁矿山产生大量的尾矿，可根据其性质研究尾矿利用的方式，尽量减少尾矿的产生。

| Abstract: | In this study, 15 large and medium-sized iron deposits in Hebei Province are studied on their spatial agglomeration characteristics, development and utilization status of iron ore resources. We analyse detailedly on the endowment conditions of iron ore resources, the similarity and heterogeneity of mining and mineral processing, the comprehensive utilization potential of associated elements and tailings in typical accumulation areas of iron ore resources. Also, the differential utilization policies of different types of iron ore are given. The research results showed that the metallogenic types in northern Hebei, eastern Hebei, and central and southern Hebei are magmatic iron deposits, sedimentary metamorphic iron deposits, and skarn iron deposits respectively. The grade of iron and the proportion of magnetite in the three types of iron deposits are in the order of magnitude, skarn iron deposits > sedimentary metamorphic iron deposits > magmatic iron deposits. The recovery rate of mineral processing are also in the same order. The associated elements TiO2, P2O5 and Sc in the magmatic iron deposits have recyclable value and therefore, research on the comprehensive utilization of these elements should be strengthened. The iron deposits exploitation leads to the production of a large amount of tailings waste and the use of tailings can be studied according to their properties to minimize their production rate and recyclable benefits. |
