Research Progress on New Environmental-Friendly Recycling Processes for Precious Metals of Gold and Silver
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.
