铂族金属在汽车尾气催化剂、化工、投资、医疗等多个领域中扮演着关键角色,是不可或缺的战略资源。中国属于铂族金属矿产资源稀缺的国家,因此从二次资源中回收铂族金属显得尤为重要。废汽车尾气催化剂作为一类重要的铂族金属二次资源,对其回收方法进行了总结和分析,重点介绍了国内外的湿法和火法回收工艺,并对这些不同工艺的优缺点进行了比较。同时,还对废汽车尾气催化剂中铂族金属回收技术的未来研究方向进行了展望,以期为铂族金属的可持续利用提供新的思路和方法。
Platinum group metals (PGMs) play a pivotal role as indispensable strategic resources in automotive exhaust catalysts, chemical industries, investments, healthcare, and other fields. China faces significant scarcity in PGM mineral resources, making the recovery of PGMs from secondary resources particularly critical. This paper comprehensively reviews and analyzes recovery methods for spent automotive exhaust catalysts, a major secondarysource of PGMs. It highlights hydrometallurgical and pyrometallurgical recovery processes developed domestically and internationally, comparing their advantages and limitations. Furthermore, future research directions for PGM recovery from spent catalysts are proposed to advance the sustainable utilization of these metals, offering innovative ideas and approaches.
