To address the environmental hazards caused by red mud stockpiling during Bayer process alumina production and achieve efficient utilization of secondary resources, this study takes Bayer process red mud as the research object. It systematically reviews the fundamental characteristics and environmental risks of red mud, focusing on the current research status of recovering valuable metals such as Fe, Al, Ti and Sc. The study provides an in-depth comparison of the operational principles and industrial application effects of different recovery processes, and analyzes the advantages, disadvantages, and applicable scenarios of each process. Research findings indicate that the physical method for Fe recovery features simple operation but achieves a recovery rate of only 55%-60%. The reduction roasting-magnetic separation method can attain a recovery rate of 87%-92.8%, albeit with relatively high energy consumption. Acid leaching methods yield relatively high leaching rates for Al, Ti, and Sc recovery, but suffer from high acid consumption. Combined processes can enhance overall recovery efficiency, though they involve complex flowsheets. Currently, the comprehensive utilization rate of red mud has increased to approximately 12%, yet a gap remains compared with that of developed countries. Front-end phase regulation, the development of green processes, the advancement of combined processes, and the preparation of high-value-added materials from red mud represent the core development directions for future valuable metal recovery from red mud. This review can provide a reference for technological upgrading within the industry.

为解决拜耳法氧化铝生产中赤泥堆存引发的环境危害问题，同时实现二次资源的高效利用，以拜耳法赤泥为研究对象，系统梳理其基本特性与环境危害，重点阐述Fe、Al、Ti、Sc等有价金属的回收研究现状，深入对比不同回收工艺的作用原理与工业应用效果，分析各工艺的优劣势与适用场景。研究发现：物理法回收Fe操作简便但回收率仅为55%~60%，还原焙烧-磁选法回收率可达87%~92.8%，但能耗较高；酸浸法回收Al、Ti、Sc浸出率较高但酸耗高，联合工艺能提升综合回收效率但流程复杂。目前赤泥综合利用率已提升至12%左右，仍与发达国家存在差距。前端物相调控、绿色工艺研发、联合工艺开发及赤泥高值化材料制备是未来赤泥有价金属回收的核心发展方向，可为行业技术升级提供参考。
