Abstract:

Deposition of copper by electrorefining process was attained to observe the effect of the additive agents on process performance (cathode purity, surface morphology, deposition rate, current efficiency and power consumption). The deposition was done in acidic media with 40 g/l and 160 g/l concentration of cupric ions and sulfuric acid, respectively. The operating parameters were utilized: electrolyte residence time 6, 4 and 2 h, electrodes spacing 15, 30 and 45 mm, with and without addition of additive agents 3, 2.4 and 40 (mg/l) of the animal gelatin, thiourea and chlorine ions respectively, current density 300 A/m2 and electrolyte temperature 35, 50 and 65oC. To clear up the produced copper properties XRF, SEM and EDX analyses were carried out.


Keywords: Copper electrorefining process, Additive agents, Purity, Deposition rate, Morphology, Electrolyte residence time, Current efficiency, Power consumption.
