Enhanced bioleaching efficiency of copper from printed ...

Cu bioleaching was mainly related to the amount of Fe 3+ that oxidized from Fe 2+ (FeSO 4 ·7H 2 O), so the oxidation rate of Fe 2+ played a major role in Cu solubilization. The abiotic groups exhibited a slow chemical oxidation of Fe 2+ in both systems (Fig. 1(a)).When different functional bacteria took part in the processes, the two systems showed a similar tendency for Fe 2+ oxidation.
