摘　　要：赤泥是一种由于长时间化学风化而形成的大宗固体废弃物,大量的赤泥以堆放为主,不仅占用了土地,还对土壤和地下水造成了严重的污染,回收赤泥中的铁可以减少赤泥的储量,创造经济效益。本文综述了目前国内外从赤泥中回收铁的方法,包括物理回收法、化学回收法和新兴回收法,结合赤泥特性,比较这些工艺的优缺点,以便迅速应用到工业中,为赤泥资源化利用提供参考,提高资源利用效率,但仍需要更多的研究来克服当前的技术困难。Red mud is a kind of bulk solid waste formed by chemical weathering for a long time.A large amount of red mud is mainly stacked,which not only occupies land,but also causes serious pollution to soil and groundwater.Recycling iron in red mud can reduce the reserves of red mud and create economic benefits.The review on the research of the iron recovery method from RM,which included the physical recovery method,chemical recovery method and emerging recovery method was focused on,combining with the characteristics of red mud,the advantages and disadvantages of these processes were discussed.It can be rapidly applied to the industry,provide reference for the resource utilization of red mud,improve the efficiency of resource utilization,and promote economic,but it still needed more investigation to overcome the current difficulties in the near future.
