摘　　要：电子废弃物(E-waste)由于其本身具有有害物质与有价元素共存的两面性特征,因此在无害化处理的同时应当充分考虑资源化的问题。一般来说,电子废物资源化在经济方面主要的驱动力是贵金属的回收,其次是其它金属元素,如铜、钴、镍、锂等。重点介绍了通过氯化火法冶金和氯化湿法冶金从电子废弃物中提取贵金属及其它有价金属的技术。Electronic waste(E-waste)has dual characteristics of coexistence of hazardous substances and valuable elements.Therefore,the problem of resource utilization should be fully considered while harmless treatment.In general,the main economic driving force of E-waste recycling is recovery of precious metals,followed by other metal elements,such as copper,cobalt,nickel,lithium,etc.The technology of extracting precious metals and other valuable metals from E-waste through chlorinated pyrometallurgy and chlorinated hydrometallurgy was introduced emphatically.
