Anodes for metal winning & refining

Electrolytically obtained metals, such as nickel, copper, and cobalt, are essential materials for a wide range of applications where purity requirements are critical.

DSA® anodes are used in various industrial sectors to recover precious metals from exhausted solutions or in small electrodeposition plants in order to minimize waste and promote closed-loop processes. 

If you operate an electrowinning plant and need efficient solutions in producing high quality and high purity products, you can benefit from:

• power savings,

• enhanced productivity,

• a lead-free plated metal cathode product, and

• no need to treat sludges poisoned by lead.

De Nora offers solutions based on metal oxide anodes (MMO anodes) used in chloride electrolyte, mixed sulfate and chloride solutions, and nitrate solutions for:

• conventional divided electrolysis cells (anodes placed in porous bags),

• undivided cells,

• cylindrical cells.

Activated metallic DSA® anodes are used to deposit the target metal on cathodes (starting sheets) to form a highly pure product that is used in different markets and applications.
