Abstract EN
The aim of the study was to recover copper and lead metal from waste printed circuit boards (PCBs).
The electrowinning method is found to be an effective recycling process to recover copper and lead metal from printed circuit board wastes.
In order to simplify the process with affordable equipment, a simple ammonical leaching operation method was adopted.
The selected PCBs were incinerated into fine ash powder at 500°C for 1 hour in the pyrolysis reactor.
Then, the fine ash powder was subjected to acid-leaching process to recover the metals with varying conditions like acid-base concentration, electrode combination, and leaching time.
The relative electrolysis solution of 0.1 M lead nitrate for lead and 0.1 M copper sulphate for copper was used to extract metals from PCBs at room temperature.
The amount of lead and copper extracted from the process was determined by an atomic absorption spectrophotometer, and results found were 73.29% and 82.17%, respectively.
Further, the optimum conditions for the recovery of metals were determined by using RSM software.
The results showed that the percentage of lead and copper recovery were 78.25% and 89.1% should be 4 hrs 10 A/dm2.
