| 中文摘要: |
| 从铂族金属二次资源中回收铂族金属，对于解决我国铂族金属的供需矛盾及可持续发展具有重要意义。火法工艺回收在工业生产上应用多、技术较成熟。本文详细总结了火法回收铂族金属工艺研究进展，其中以铅、铜、铁、锍等金属捕集法在工业上应用较多、技术较成熟，其中铁捕集法、铜捕集法回收率高、发展前景广阔；高温氯化挥发法对设备要求高、产生有毒气体；焚烧法仅适用于处理炭质载体催化剂；未来需针对火法回收工艺中存在的相关问题进行深入基础研究，同时开发高效清洁回收新方法，实现我国铂族金属二次资源的高效清洁循环利用。 |
| 英文摘要: |
| The recovery of platinum group metals from secondary resources is of great significance for solving the contradiction between the supply and demand and sustainable development of platinum group metals in China. Pyroprocess methods are widely used in industrial production, and they are relatively mature. This paper summarized the research progress of the recovery of platinum group metals by pyrolysis in details. Among these methods, lead, copper, iron, matte and other metal collections are widely applied in industry and more mature technology. The iron and copper collection methods have high recovery rates and promising development prospects. The high temperature chlorination and volatilization method requires expensive equipment and produce toxic gases. The incineration method is only suitable for treating carbon supported catalysts. In the future, it is necessary to conduct in-depth basic research on the related problems in the pyroprocess recovery processes, and at the same time develop new efficient and clean recovery methods to realize the efficient and clean recycling of secondary resources of platinum group metals in China. |
