Metals low in activity series like copper are very unreactive. The oxides of these metals can be reduced to metals by heating alone. Copper is found as Cu2S in nature. It can be formed just heating it in air.

2Cu₂S+3O₂→ Heat 2Cu₂O+SO₂↑

2Cu₂O+Cu₂S Heat → 6Cu+SO₂↑

<div>Then electrolytic refining of copper is carried out to remove the rest of the impurities present in the ore. The impure copper is made anode and strip of pure copper are made cathode. On passing the current as shown in the diagram, the pure copper from the anode dissolves into an electrolyte. An equivalent amount of copper is deposited on the cathode. Soluble impurities remain in the solution, whereas insoluble impurities settle at the bottom of the anode.</div>
