摘　　要：赤泥是氧化铝生产过程中排放的具强碱性和放射性的固体废料,产量大而利用率极低,大量堆放会造成严重的环境问题。综述了赤泥在有价金属回收、建筑材料生产以及环境保护等领域的资源化利用现状,梳理了赤泥建筑材料放射性的研究进展,讨论了赤泥综合应用过程中存在的问题和不足,同时对赤泥资源化利用的发展方向进行了展望。Red mud,a byproduct of alumina production,is a solid waste known for its elevated alkalinity and radioactivity.Despite its substantial quantity,it is presently underutilized and posing potential environmental concerns due to excessive accumulation.This paper reviewed the current utilization of red mud resources for metal extraction,construction material production,and environmental safeguarding.It also explored recent research progress in incorporating red mud into building materials,particularly in relation to its radioactivity.Additionally,it addressed the obstacles and deficiencies in the extensive application of red mud,while also proposed potential future avenues for its resource utilization.
