网页An overall equation for this series of steps is: 2CuFeS2 + 2SiO2 + 4O2 → Cu2S + 2FeSiO3 + 3SO2. The copper (I) sulfide produced is converted to copper with a final blast of air. Cu2S + O2 → 2Cu + SO2. The end product of this is called blister copper a porous brittle form of copper, about 98 99.5% pure.
