Copper electrowinning: theoretical and practical design

The electrowinning of copper ions from leaching and solvent extraction plays a crucial role in the global copper supply chain. This paper aims to examine the essential theoretical and practical aspects involved in designing copper electrowinning plants. The methodology includes a comprehensive review of fundamental equations, principles governing the electrolysis of copper, and the practical requirements necessary for effective plant design. The findings reveal critical theoretical factors such as current density, efficiency, electrolyte ion concentrations, cell voltages, and electrode characteristics that significantly influence the design process. Additionally, practical considerations encompass various elements such as plant location, layout, equipment materials, production cycles, and quality control management. By synthesizing both theoretical insights and practical implications, the paper outlines a framework that facilitates the efficient design and construction of copper electrowinning facilities, ensuring they are cost-effective, operationally flexible, and capable of meeting product quality standards. This combined approach ultimately enhances the understanding and optimization of copper electrowinning processes, benefiting industries reliant on copper extraction and processing.
