摘要
随着电子工业的迅速发展,作为生产原料之一的贵金属的消耗量越来越大。科学、合理、高效的回收利用电子废弃物中的贵金属,既可以节约资源能源,又能达到保护环境的目的。在此,阐述了电子废弃物中贵金属的回收处理技术,介绍了各种技术的基本原理和研究进展,并简要介绍了已经应用于工业生产的贵金属回收工艺流程。
Because of the rapid development of electronic industry, as one of the raw materials, the amounts of precious metals consumed are larger and larger. Precious metals in electronic waste should be disposed and recycled rationally and efficiently. We should not only save nature and energy sources but also protect environment from pollution. Several technologies were presented for recycling precious metals in electronic waste. The principium and studying status of each recycling technology were reviewed and some recycling courses applied in industry were also introduced briefly.
