Copper electrowinning

The new frontier of Mixed Metal Oxide Anodes


Energy and chemical savings

Clean operation

Cathode quality improvement

Safety and Healthcare

Mixed metal oxide (MMO) coating titanium anodes are gaining acceptance even in copper electrowinning versus lead alloy anodes, still found in the majority of commercial metal electrowinning plants.
Primary copper producers have already proved the advantages of titanium anode technology over conventional lead anodes: energy and chemical saving, clean operation, occupational safety and healthcare and improvement in cathode quality.
De Nora’s solution for copper electrowinning includes latest generation energy-saving electrocatalytic coating and a patented engineered titanium structure with breakthrough dendrite mitigation system for self-protection against short circuits.  The development of a monitoring system completes the package.
