An overall equation for this series of steps is: 2CuFeS2 + 2SiO2 + 4O2 → Cu2S + 2FeSiO3 + 3SO2 (1) The copper (I) sulfide produced is converted to copper with a final blast of air. Cu2S +O2 → 2Cu + SO2 (2) The end product of this is called blister copper-a porous brittle form of copper, about 98-99.5% pure.
