Platinum group metals (PGMs) are widely applied in the field of catalysts due to their excellent catalyst activity and high-temperature stability. The rapid generation of the waste catalyst has become the significant characteristic of PGMs with the accelerating consumption of limited PGMs nature resources. It is necessary to recover/recycle PGMs from a waste catalyst for both economic and environmental benefits. This paper reviews the PGMs recovery from waste catalysts using a metals smelting-collection process, which belongs to the main pyrometallurgical process, in the presence of various metal collectors, such as lead, copper, iron, matte, print circuit board (PCB) or reactive metals of calcium and magnesium. The current status of recovery of PGMs from waste catalysts through the addition of various metals as the collector is discussed and existing advantages and challenges are highlighted in this paper. Meanwhile, in the view of the promising processes of PGMs recovery, the influencing factors such as the economic, environmentally friendly, sustainable recycling, commercial scale, and low-grade materials are considered.

铂族金属（PGM）由于其出色的催化剂活性和高温稳定性而被广泛应用于催化剂领域。随着有限的PGMs自然资源的消耗加速，废催化剂的快速产生已经成为PGMs的重要特征。为了经济和环境效益，有必要从废催化剂中回收/回收铂族金属。本文回顾了在存在各种金属收集器（例如铅，铜，铁，磨砂，印刷电路板（PCB）或印刷电路板）的情况下，通过属于主要火法冶金过程的金属冶炼收集工艺从废催化剂中回收铂族金属的方法。钙和镁的活性金属。讨论了通过添加各种金属作为捕收剂从废催化剂中回收铂族金属的现状，并着重指出了现有的优势和挑战。同时，鉴于铂族金属回收的前景广阔，考虑了经济，环境友好，可持续回收，商业规模和低品位材料等影响因素。
