· The use and value of copper are high and so there are both environmental and economic drivers for recovering copper efficiently. Redundant Printed Circuit Boards (PCBs) constitute a rich source of copper. The focus of this work is the demonstration of ‘closed-loop’ recycling of copper from PCBs via bioleaching and electrowinning processes.
· This work is targeting copper the most abundant metal in e-waste that represents up to 20 by weight of printed circuit boards (PCBs). In the first stage bioleaching was tested for different pulp densities (0.25–1.00 w/v) and successfully used to extract multiple metals from PCBs using the acidophilic bacterium Acidithiobacillus ferrooxidans.
· 1. Introduction. Printed circuit boards (PCBs) exist in all electrical and electronic products providing a bridge between software and hardware. In recent years the average growth rate of printed circuit board industry in the world is 8.7 but the statistics for Southeast Asia (10.8 ) and mainland China (14.4 ) are much higher (Huang et al. 2009).
· The plant production capacity has significant influence on the internal rate of return of the process and cost to benefit ratio due to its large capital investment. It is at least 30 000 tonnes/annum for the plant capacity of e-waste recycling through copper smelting that can be economically viable (Ghodrat et al. 2016). Therefore advanced

· Due to economic and societal reasons informal activities including open burning backyard recycling and landfill are still the prevailing methods used for electronic waste treatment in developing countries. Great efforts have been made especially in China to promote formal approaches for electronic waste management by enacting laws developing green recycling technologies initiating pilot
· The reutilization rate of copper in waste circuit board is up to 99 after separating and sorting. After being broken for three times the waste circuit boards become a mixture of metal and resin fiber powder. Then the metal and the resin powder are separated by the separation of air separator and electrostatic separator.
