design and build a copper electrowinning plant. Part 1: Copper electrolysis theoretical considerations Faraday's law For the winning of copper by the addition of electrons [1] Cations go towards the cathode, and anions go to the anode. The working electrode is where reduction takes place and the counter electrode is where oxidation occurs. The
In copper electro-refining the copper anode and copper deposit on the cathode leach very slowly in electrolyte, and do not set up a galvanic couple. In electrowinning however the copper on the cathode and the lead anode do set up a reverse voltage. The resultant reverse current flow can have dramatic impacts on electrodes and copper product:
