In the extraction of copper from its sulphide ore, the metal is formed by reduction of Cu2O with: — Metallurgy and Isolation of Elements Chemistry Question

💡 Solution & Explanation

Step 2: During the self-reduction process, copper(I) oxide (Cu2O) is reduced to metallic copper by reacting with the remaining copper(I) sulfide (Cu2S) at high temperatures. Step 2: The reaction is: 2Cu2O + Cu2S -> 6Cu + SO2. Step 3: Thus, the reduction of Cu2O is carried out by Cu2S, which corresponds to option (c).
