摘　　要：赤泥中碱性物质含量较高是赤泥不能大规模资源化利用的主要原因。对国内外赤泥资源化利用方面的研究进行归纳概括,介绍了赤泥的物理特性、化学成分以及赤泥在除碱和工程方面的研究成果,总结了赤泥在工程领域、环保领域和提取金属元素等方面的应用,论述了赤泥的资源化利用研究现状,提出了赤泥在除碱、提取金属、建筑应用、堆存等各方面存在的问题。研究认为,赤泥是一种具有特殊岩土工程性质的特殊土,需土量巨大的路基工程和充填工程将成为赤泥大规模资源化利用的有效途径。The main reason why red mud cannot be utilized in large scale is the high content of alkaline substances in red mud.This paper summarized the research on red mud resource utilization at home and abroad,introduced the physical characteristics,chemical composition and the research on alkali removal and engineering of red mud.This paper summarized the application of red mud in engineering,environmental protection and extraction of metal elements,and discussed the current research situation of red mud resource utilization,and put forward the existing problems of red mud in the aspects of alkali removal,metal extraction,construction application and stacking.It was considered that the red mud is a special soil with special engineering properties and roadbed engineering and filling engineering with huge soil demand will become an effective way for large-scale utilization of red mud.
