Abstract:Cuprous chloride hydrochloric acid solutions were electrolysed in a two compartments cell without agitation for copper extraction. It is found that the current density affects the colour and the size of copper deposits. During electrodeposition of copper from cuprous solution in the presence of various concentrations of lead, zinc or iron ions at different current densities, it is observed that lead is codeposited with copper by increasing current density. In all experiments, the current efficiency for the copper deposition reaction fluctuates between 88.50% and 95.50%.

 

Key words: electrodeposition; codeposition; current efficiency; cuprous chloride solution
