Metals refining and recovery is the process of recovering metal from an electrolytic solution by electrochemical plating on a cathode, using an insoluble anode in the most advanced processes, to obtain pure, high-value metals ready for industrial use.

Refining allows the purity levels required in the electronics, energy, automotive, and manufacturing sectors to be achieved.

Recovery maximizes the yield of metals such as copper, nickel, cobalt, and precious metals from raw or secondary sources.

Metals refining and recovery are essential. Without effective refining, impurities compromise performance and reliability, while recovery prevents valuable resources from being lost.
De Nora plays a key role by providing advanced mixed metal oxide (MMO) anodes that ensure:

High-purity metal recovery.

De Nora's DSA® mixed metal oxide (MMO) anodes are used to deposit target metals —such as nickel, cobalt, copper, and precious metals — onto cathodes during refining and recovery.
These anodes eliminate the need to use alternatives to lead, producing highly pure metals.
Some of the MMO anode applications include:

  • nickel and cobalt electrowinning production;

  • precious metal refining (gold, silver, rhodium);

  • recovery of copper from bleed streams;

  • retrieval of valuable metals from industrial wastewater.

Energy savings & productivity improvement.

De Nora’s MMO anodes deliver significant power savings and enhanced productivity in electrowinning operations. By replacing lead-based systems, they increase efficiency, achieve cleaner results, and eliminate sludge contamination issues.

Long service life & proven track record.

Supported by over five decades of experience, De Nora’s DSA® anodes are widely adopted—more than 50,000 units deployed in electrowinning and recovery plants globally.
These anodes support both large-scale refiners and compact electrowinning setups, promoting sustainable, closed-loop operations.
