An electrolysis cell with rotating cylinder cathode was used to recover copper from copper galvanotechnique industry rinse waters. The effects of cathodic current density, cathode rotating speed, electrolyte temperature and cathode-scraper distance on copper recovery were investigated. Optimum conditions for maximum copper recovery were found as 1000 A/m(2) cathodic current density, 250 min(-1) cathode rotating speed, 60 degreesC electrolyte temperature, and 1 mm cathode-scraper distance. Final copper concentration was 3 mg/L by the experiments run under these conditions, with 3.3 kWh/kg Cu specific energy consumption and 85% current efficiency.
