Abstract: Many methods are reported in the literature for the synthesis of copper particles from Waste Printed Circuit Boards (WPCB’s). In this present study, the synthesis of copper particles was achieved using Hibiscus rosa-sinensis plant extracts from the leachate product of Waste Printed Circuit Boards (WPCB’s) using organic acids. Natural citric acid and tartaric acid were used for the separation of the copper particles from WPCB’s. The investigation was carried out at different time periods. The influence of time was found to be significant on the leaching capacity of the acids, which was found to increase with increase in temperature. The synthesis of copper particles was analyzed using SEM and EDAX. The optimum conditions for the leaching of copper were found to be at 60° C, 120 rpm and 24hr.
