Unlike conventional cementation processes, we utilized a novel electro-assisted cementation (EAC) process to improve Cd removal from Zn processing wastewater. Additionally, we investigated Cu recovery from Cu smelting flue dust (CSFD) leachate using the same EAC process. Leveraging electrochemical principles, the EAC process improves metal recovery efficiency. Under optimized conditions, we achieved 98.5% recovery of dissolved Cd at 94.1% purity. Similarly, EAC enabled 98.2% removal of Cu from CSFD leachate.
