    Electrodeposition finds applications in recovering metals from copper indium gallium diselenide (CIGS) solar cells. After leaching and solvent extraction, indium is recovered by electrodeposition (Tunsu and Retegan, 2016). Another method of metal recovery from CIGS is the separation of selenium followed by dissolution with mineral acids.

    The leached liquor has been successfully treated with an electrowinning process, to recover copper and nickel. The copper and nickel depositions, were performed in acid and alkaline conditions, respectively. The Faraday yield was of about 95%. The energy consumption was 2.13 and 4.43 kWh per kg of copper and nickel recovered, respectively. At the end of the process, about 94-99% of the initial
