Base Metal Electrowinning

Winning with Electrode Design to Reduce Energy Costs in Traditional Processes


Since 1972, De Nora strives to improve anode coatings to better serve nickel. Today there are more than 40,000 De Nora DSA® anodes installed in Electrowinning tank houses and recovery operation plants worldwide. These Electrowinning tank houses excel at providing optimum quality for recovering metal and are highly efficient. We also offer a wide array of energy-efficient products for the electrowinning of non-ferrous metals.

Some of the applications of our titanium DSA® anodes include nickel production, precious metal refining (gold, silver), recovery of copper from bleed streams, and retrieval of valuable metals from industrial wastewater.

The use of De Nora titanium insoluble anodes in electrowinning applications is beneficial because they save power, enhance productivity and improve operation.

De Nora’s R&D department continues to develop new products for copper and zinc electrowinning.   We are constantly looking for innovative solutions that guarantee performance improvements that are technical and cost-effective.
