Electrolysis process of copper

When current is applied to the electrolysis cell copper (II) ions in solution are reduced to copper atoms at the cathode. Copper atoms on the anode are oxidized to copper (II) ions. The cathode gains mass, the anode looses mass. When the experiment ends, the electrodes are dried and the mass of each electrode weighed on the mini-balance

    Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning)
