铁矿废石综合利用研究进展

随着我国铁矿资源的不断开采，不可避免地产生大量废石，伴随着绿色矿山理念的深入，这些铁矿废石的处理及利用一直是各地矿山企业关注的热点和难点。当前，我国对铁矿废石的处理手段主要包括采空区回填、工程运用、回收铁矿石以及制备砂石骨料等多种方式。本文在介绍当前我国铁矿废石资源基本情况的基础上，综述了近些年来国内外铁矿废石资源的综合利用研究进展，以期为我国未来矿山废石处理问题的解决提供借鉴与参考。 

Research Progress on Comprehensive Utilization of Iron Ore Barren Rock

With the continuous exploitation of China's iron ore resources, it is inevitable to produce a large number of waste rocks. As the concept of a green mine is deeply rooted in the hearts of the people, the treatment and utilization of these iron ore waste rocks have always been a hot and difficult issue for mining enterprises. At present, the treatment methods for waste rock in iron ore mainly include goaf backfilling, engineering application, recovery of iron ore and preparation of sand and gravel aggregate. Based on the introduction of the basic situation of iron ore waste resources in China, this paper summarized the research progress of comprehensive utilization of iron ore waste resources in China and other countries in recent years, in order to provide a reference for solving the problem of waste rock storage in China in the future.
