摘要

摘要:
铁尾矿的大量堆存不但会产生尾矿库安全隐患、污染环境，而且也浪费了其中大量的有价组分，不符合国家建设资源节约型、环境友好型社会的要求。因此，如何充分利用铁尾矿，实现二次资源的综合利用已成为目前的研究热点。本文从阐述铁尾矿的分类开始，详细介绍了铁尾矿有价元素的回收，铁尾矿制备建筑与填筑材料、装饰材料、制备肥料及土壤改良剂以及化工产品等方面的研究现状，最后探讨了铁尾矿利用未来发展前景并提出相关建议。

Abstract:
At present, the storage capacity of iron tailings in China has reached over one billion tons. Not only the potential safety hazards of tailing dam and environments pollution will be produced, but also a large number of valuable components will be wasted. It does not meet the requirements of the country to build a resource−saving and environment−friendly society. Therefore, how to realize comprehensive utilization of secondary resources has become a research hotspot at present. In this paper, the classification of iron tailings is introduced first. Then, the research status of valuable elements recovery from iron tailings, the preparation of construction and filling materials, decorative materials, the preparation of fertilizers, soil amendments, chemical products are systematically summarized. Finally, the future development prospects of iron tailings utilization are discussed and the relevant suggestions are puts forward.
