摘要
贵金属广泛应用于工业领域,属于不可再生资源,供需矛盾日益突出.从二次资源中回收贵金属,可有效缓解我国贵金属资源严重匮乏的问题,具有重要的战略意义.本文综述含贵金属金、银的二次资源的可持续回收技术,重点分析选择性溶解、选择性沉淀、溶剂萃取、膜分离和电化学还原等新技术,并对环境友好型贵金属回收技术进行展望,以更好地从二次资源中回收金、银.
Abstract
Precious metals are widely used in the industrial field and belong to non renewable resources,with increasingly prominent supply-demand contradictions.Recycling precious metals from secondary resources can effectively alleviate the serious shortage of precious metal resources in China,and has important strategic significance.This paper reviews sustainable recycling technologies for secondary resources containing precious metals such as gold and silver,with a focus on analyzing new technologies such as selective dissolution,selective precipitation,solvent extraction,membrane separation,and electrochemical reduction,and also looks forward to environmental-friendly precious metal recycling technologies,so as to better recycle gold and silver from secondary resources.
