(a) Explain the steps for extraction of copper from its ore. Write the reaction involved.
(b) Draw a neat, labelled diagram for electrolytic refining of copper and explain the process.

Explanation

At anode : `rarr Cu rarr Cu^(2+) + 2^(e-)`
At cathode `rarr Cu^(2+) + 2^(e) rarr Cu`
Detailed Answer :
Electrolytic refining :
At anode : `Cu(s) rarr Cu^(2+) (aq) + 2e^(-)`
At cathode : `Cu^(2+)(aq) + 2e^(-) rarr Cu(s)`
