This issue documents research and development activities that utilize electrochemical principles and techniques to achieve practical objectives in applications ranging from processing crude ore to production of value-added materials. The focus will be on identifying opportunities for future progression that utilize the latest understanding of electrochemical mechanisms in processing systems.

"The sixth International Symposium on Electrochemistry in Mineral and Metal Processing was held during the 2003rd Meeting of the Electrochemical Society, Inc., in Paris, France, May 14-18, 2003."--p. iii.

Extensively revised and updated, this edition provides the broad base of knowledge required by all working in the gold extraction and gold processing industries. It bridges the gap between research and industry by emphasizing practical applications of chemical principles and techniques.

This issue of ECS Transactions contains papers on electrochemical aspects of concentrating and extracting base, precious and light metals from their ores and secondary materials, and associated energy and environmental considerations. Both fundamental and applied work is covered with emphasis on recent progress in: (1) mineral flotation, (2) hydrometallurgy, (3) electrowinning and refining, (4) environmental technologies associated with mineral and metal processing, (5) electrochemical methods for secondary metal production, and (6) recovery of metals from wastes.
