Abstract:

Recovery of copper from the sludge of printed circuit board (PCB) was carried out in the process of leaching and electrowinning. Influences of electric current, temperature, pH value and electrode distance on copper electrowinning were investigated. The result indicates that the proposed leaching conditions are as follows: pH value of 1.4, electric current of 300 A/m2, electrode distance of  5 cm, treatment time of 20 h, and temperature of 40 ℃. 

Key words: printed circuit board （PCB）; sludge; leaching; electrowinning；reutilization
