According to the properties of bioleaching solutions of printed circuit boards (PCBs), copper in the leaching solution were recovery by ion exchange with macroporous styrene iminodiacetic acid chelating resin D401. The bed height of resin, flow rate, pH value on copper adsorption had been studied. Work Exchange Capacity (WEC) of copper increased with increasing bed height of resin and flow rate. The...
According to the properties of bioleaching solutions of printed circuit boards (PCBs), impurities in the leaching solution were removed by solvent extraction with N902 (2-hydroxy-5-nonylbenzaldoxime), then the purified solution was subjected to electrolyse for the production of metallic copper. The influence of equilibration time, extractant concentration, O/A ratios, pH value on copper(II) extraction...
Microbiological processes were applied to mobilize metals from printed wire boards. Acidithiobacillusferrooxidans isolated from a acidic mine drainage was grown and acclimated in the presence of printed wire boards and then used as bioleaching bacteria to solubilize metals from scraps of printed wire boards. Two Face Copper Clad Laminate (TFCCL), TFCCL with green non-conductive coating and actual...
