The copper recovery from the etching effluent using electrodialysis was experimentally studied. Cupric ions was separated and concentrated from the strong hydrochloric acid-based copper containing etching effluent with electrodialysis. After the concentration, copper have been recovered in the form of copper oxides via electro-basification. The effects of the operating parameters such as a cupric ion concentration, a chloride ion concentration, and a current density have been examined.
