| 摘 要： | 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 isIn all experiments, the current efficiency for the copper codeposited with copper by increasing current density.deposition reaction fluctuates between 88.50% and 95.50%。
