摘要
对贵金属二次资源的特点、来源、预处理方法以及金银铂钯等贵金属的回收利用方法等进行综合评述,提出了在无害化处置贵金属废料时应充分考虑回收利用工艺的全面性、尽可能以废治废、生物处理、集中处理、政府积极参与协调并加大投入,对于目前暂时无法做到无害化处置的贵金属废料,将这些废料暂时集中放置,滞后处理等有价值的建议。
The waste material of precious metals is an important secondary resource. How to increase the utilization of these waste materials and treat them innoxiously is an important problem, and have drawn a wide attention around the world. In this paper, the characterization, origination, pretreatment methods of waste materials of precious metals and the recovering technology of gold, silver. platinum and palladium from above waste materials have been reviewed. Several suggestions about innoxious treatment on the waste materials of precious metals have been proposed.
