Electrolytic recovery of copper from dilute solutions

高达10%返现 The electrolytic recovery of copper is one of the methods of preventing the formation of sludges generated by conventional treatments. Electrolysis of metal ions in dilute solutions using vertical electrodes results in low recovery. Therefore, a design consisting of a rotating tubular bed reactor with extended cathode surfaces was developed to improve the mass transfer in the cell.
