E-waste is an important secondary source of precious metals. Especially discarded printed circuit boards (PCBs) contain high concentrations of precious metals. In recent years, the bacterial leaching was more widely preferred due to its low environmental impact and cost in the recovery of these precious metals. In this study, a PCBs-adapted …

The bioleaching ability of the isolated organism was analyzed using ICP-OES, and the results are presented in Table 1. Fifty-seven percent of copper and 32% of nickel were leached by the organism after the one-step leaching at a temperature of 30 °C (shaking condition (120 RPM) for 7 days) (Fig. 3A). Increasing the period of incubation …

To identify which is spontaneous we used the activity series (review section 3.6.1.1) and from table 3.6a we see that zinc is more active than copper, meaning metallic zinc will spontaneously dissolve in a solution with Copper (II) ions. This means the top reaction above has a negative free energy (it is spontaneous) and could be used to do ...
