Project background

A metal-processing project needed to evaluate anode options for an electrowinning or metal recovery process. Typical projects include copper, zinc or nickel electrowinning lines and mining / metallurgical EPC work, where electrolyte composition, current density, anode life target and tank interface all affect configuration.

Customer typeHydrometallurgy or electrowinning plant
Project stageAnode replacement, upgrade or new cell evaluation
TJNE deliverableCoated titanium anode suitability and operating-condition review

Key technical questions

  • What metal system, electrolyte composition, acid concentration and impurities are present?
  • What current density, temperature, tank geometry and electrode spacing are planned?
  • Is the requirement for replacement anodes, a new cell design or pilot testing?

TJNE review and supply scope

  • Titanium anodes or special coated anodes reviewed against electrolyte conditions
  • Geometry and connection review based on existing tank or cell design
  • Project input list for electrowinning and metal recovery projects

Result / next step

The enquiry is converted into an electrolyte-compatibility and operating-target review, helping the buyer compare coating direction, anode geometry and tank-interface assumptions before proposal.

Note: Similar applications are reviewed against confirmed operating conditions, drawings and supply scope before final configuration.
