摘　　要：在计算机和手机革命之后,电器和电子垃圾成为对城乡社区的严重威胁。在发展中国家,预防危险暴露和适当管理具有挑战性。将危机转化为机遇的一种方法是从这种废弃电子电气设备(WEEE)中提取金属,这可将废物转化为金属矿石。微生物的参与可以通过一种生态友好的技术方式来减少对自然环境的伤害,进而增加收益。本文回顾了生物浸出过程中涉及的机制、使用的微生物、用到的方法和限制情况,以及从WEEE中金属的生物浸出过程的最新进展和未来展望。After the computer and mobile revolution,electric and electronic waste had become a serious threat to urban and rural communities equally.Prevention of the hazardous exposure and proper management are challenging in developing nations.One way to turn the crisis to opportunity is to extract metals from this Waste Electronic and Electric Equipment(WEEE)is making waste into a source of metal ores.The involvement of microbes in this technology could increase the boons by being an eco-friendly technique for reducing the hazardous nature.This article reviews the mechanisms involved in the process of bioleaching,the microorganisms employed,methods used and various developments as well as limitations along with recent advances and future prospects of the process of bioleaching of metals from WEEE.
