Can copper be extracted by electrolysis

2021-2-23  During the electrolysis of copper (II) sulfate, or CuSO4,the deposition of copper can be seen on the cathode; at the same time, the anode will be dissolved by the process. In electrolysis, the cathode is the negative electrode, while in galvanic cells it acts as the positive electrode.
