The application examples of bioleaching technology in the field of electronic waste

Waste printed circuit boards(PCB) is a typical electronic waste, which contains a variety of metals and non-metal, if they are disposed improperly, not only will cause loss of resources, but also harmful to environment and human health. Microbial technology is applied to the extraction of metals from electronic waste because of its environmental friendly features. Bioleaching metals from gantry pylons, PCB and the sludge from PCB production line were reviewed in this article. The current use of microbial technology in electronic waste among the optimal experimental conditions, strain selection and domestication were also explored, finally, the application foreground and development of microbial technology is prospected on this basis.
