废旧线路板湿法浸出金的研究进展

Research Progress on Hydrometallurgical Leaching of Gold from Waste Printed Circuit Boards

随着各类电子产品的逐渐普及,手机、计算机等电子产品短时间淘汰,催生大量的电子废物。电子废物中的废旧线路板(WPCBs)易造成环境污染,且处理形势日趋严峻。废旧线路板的金资源化技术不仅有利于减轻电子废物对环境的污染,而且有利于促进金资源的二次利用,具有良好的环境效益和经济效益。本文综述了湿法冶金工艺浸出废旧线路板中金的研究进展,可以为今后研究并改进金资源化技术、实现产业化提供理论指导。

With the gradual popularization of various electronic products,electronic products such as mobile phones and computers have been eliminated in a short period of time,resulting in a large amount of electronic waste.The waste printed circuit boards (WPCBs) in the electronic waste are easy to cause environmental pollution,and the disposal situation is becoming more and more serious.The gold resource recovery technology of WPCBs is not only conducive to reducing the pollution of electronic waste to the environment,but also conducive to promoting the secondary utilization of gold resources,which has good environmental and economic benefits.This paper summarizes the research progress of hydrometallurgical leaching of gold from WPCBs,which can provide theoretical guidance for future research and improvement of gold resource technology and industrialization.
