Question

How is copper extracted from its ores

Answer 1

Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. ... This trickles slowly through the ore dissolving copper to form copper sulfate. The copper is recovered by electrolytic refining

Answer 2

Answer:

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 Cu2​S in nature. It can be formed just heating it in air. 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.
