Cathode
Permanent Cathode Technology is a modern and highly efficient system used in copper production processes such as Copper Electrorefining and Copper Electrowinning. The technology utilizes reusable stainless steel cathode plates that serve as a permanent substrate for copper deposition, replacing the traditional starter sheet method.

Met-Tech provide permanent cathode technology, made from Stainless Steel or Ti material to users. Up to date, over 700.000 permanent cathodes sold over the world, are producing copper.

Key advantages of Permanent Cathode Technology include:
  • Higher cathode quality and consistent copper purity
  • Reduced operating and labor costs
  • Improved process efficiency and productivity
  • Enhanced safety through automation and reduced manual handling
  • Longer service life compared to conventional starter sheets

Cathode Refurbishment Services
Cathode refurbishment is an essential maintenance process designed to extend the service life and maintain the performance of permanent cathodes used in Copper Electrowinning and Copper Electrorefining operations.

During long-term operation in tankhouse environments, stainless steel permanent cathodes are exposed to mechanical wear, chemical corrosion, and physical damage. These conditions may affect cathode flatness, edge protection, electrical conductivity, and overall stripping performance. Cathode refurbishment restores the cathodes to their original operational standards, ensuring reliable performance and high-quality copper production.

Typical refurbishment activities include:
  • Inspection and evaluation of cathode condition
  • Straightening and flatness correction
  • Replacement or repair of edge strips and insulators
  • Surface cleaning and polishing of stainless steel plates
  • Repair or replacement of hanger bars and electrical contact areas
  • Reassembly and quality control testing

Refurbishment programs significantly reduce operating costs by extending cathode service life and minimizing the need for complete cathode replacement. Properly refurbished cathodes help maintain uniform copper deposition, improve stripping performance, and ensure consistent product quality.

Regular cathode maintenance and refurbishment also contribute to improved tankhouse efficiency, reduced downtime, and enhanced operational reliability. For many copper operations, a structured cathode refurbishment program is a cost-effective strategy for maintaining optimal tankhouse performance.
