Short Course Fundamentals and Practice of Copper Electrorefining and Electrowinning – Performance of Lead Anodes During Cu Electrowinning

Lead anode performance represents a critical factor in the operational efficiency, product quality, and economic competitiveness of copper electrowinning operations. Dr. Andreas Siegmund of Quemetco and RSR Technologies developed this specialized short course to address the complex metallurgical, electrochemical, and mechanical factors that influence lead anode service life and performance in industrial copper recovery facilities. As copper producers seek to optimize electrowinning productivity while minimizing anode replacement costs and operational disruptions, understanding the fundamentals of lead anode systems becomes essential for metallurgical and maintenance personnel.

This comprehensive short course examines lead anode system design, materials selection, and manufacturing processes, including detailed comparison of cast versus rolled anode production methods. Dr. Siegmund provides technical analysis of alloying element effects on anode performance, exploring how minor additions of silver, calcium, and other elements influence corrosion resistance, mechanical strength, and electrical conductivity. The course addresses critical operational parameters that affect anode longevity, including current density, electrolyte composition, temperature control, and electrode spacing.

Corrosion mechanisms affecting lead anodes in acidic copper sulfate electrolytes receive extensive attention in this training program, with detailed examination of passivation layer formation, corrosion product behavior, and the relationship between operating conditions and anode degradation rates. Understanding these fundamental electrochemical processes enables electrowinning operators to implement maintenance strategies that extend anode service life, reduce replacement frequency, and maintain consistent current efficiency throughout the anode lifecycle.

For copper electrowinning facilities seeking to optimize anode performance and reduce operating costs, this short course provides essential technical knowledge and practical guidance. Dr. Siegmund's expertise in lead metallurgy and electrochemical systems offers participants insights drawn from decades of industry experience and research in non-ferrous metal production.
