摘要
铂族金属(Platinum Group Metals,PGMs)是我国关键战略资源。其回收利用备受关注。铁捕集法作为主流火法工艺,所获Fe-PGMs合金结构致密、化学惰性强,难以破碎处理,制约后续富集与提纯。湿法工艺在处理此类合金时面临诸多挑战,如酸耗量大、生产成本高以及环境污染严重等。因此,如何从Fe-PGMs合金分离出PGMs成为解决问题的关键。综述了Fe-PGMs合金在富集前预处理阶段的工艺技术现状,评估了各工艺的优缺点。
Platinum Group Metals(PGMs)are key strategic resources in China.Their recycling and utilization have attracted much attention.As the mainstream pyrometallurgical process,the iron capture method produces Fe-PGMs alloy with a dense structure and strong chemical inertness,which is difficult to crush and treat,and restricts subsequent enrichment and purification.Wet process technology faces many challenges in processing such alloys,such as high acid consumption,high production costs,and severe environmental pollution.Therefore,how to separate PGMs from Fe PGMs alloy has become the key to solving the problem.This paper summarizes the current status of the pre-treatment process for Fe-PGMs alloys before enrichment,and evaluates the advantages and disadvantages of each process.
