Abstract

Language:

In the present study, a model of closed-loop recycling of copper from waste printed circuit boards (PCBs) was developed utilizing bioleaching and electrowinning processes. The objective was to evaluate the effectiveness of microbial extraction methods in recovering copper while minimizing environmental impact. The methodology involved the use of specific bioleaching bacteria to solubilize copper from PCBs, followed by electrowinning to recover the metal in a pure form. Various parameters, such as pH, temperature, and time, were optimized to enhance copper yield. The results demonstrated a significant recovery of copper from the PCBs using the proposed method, highlighting the potential of this approach for sustainable recycling in the circuit board industry. The findings indicate that bioleaching combined with electrowinning not only provides an effective means of metal recovery but also contributes to the circular economy by reducing waste and promoting resource conservation.
