What happens when copper oxide is reduced using carbon?

 · 2CuO + C CO2(g) + 2Cu CuO is reduced because the oxidation number of copper decreases from +2 (in CuO) to 0 (in Cu). C is oxidised because the oxidation number of carbon increases from 0 (in C) to +4 (in CO2). So this can be considered a redox reaction as both reduction and oxidation occurs at the

Copper extraction
