Abstract
In the present scenario, the e-waste from the various electronic sectors has been increasing due to increased utilization of electric components. In this chapter, the bioleaching(biomining) process of a computer printed circuit board (CPCB) is illustrated to extract the metal components. Basic concepts for e-waste management, their impacts, and various e-waste treatment methods have been explained. The various existing conventional metal extraction methods for the wasted CPCB have also been explored. Definitions, types, cryogenic bioleaching (biomining), influencing factors, and procedures of the bioleaching process have been illustrated. The microbiological methods for the processing of e-waste, the selection of process parameters, and the optimization or maximization of metal extraction processes were demonstrated to promote the e-waste management processes.
