Coated titanium anodes

Metso Outotec coated titanium anodes are a sustainable and energy-efficient alternative to conventional lead anodes in modern electrowinning operations. By removing lead from the process, copper cathode quality is improved and lead sludge is eliminated, which both reduces manual work and improves health and safety for employees, as well as increasing the sustainability of the process.


  • Significantly reduced energy cost compared to lead anodes.
  • Improved copper cathode quality.
  • Eliminating lead sludge means less manual work, a healthier and safer working environment, and a more sustainable process.
  • No cobalt sulfate needs to be added to the electrolyte.
  • Suitable for electrowinning processes where the main anodic reaction involves chlorine evolution.
