metallurgy Extraction of copper from chalcopyrite

Extraction of copper from chalcopyrite. During the extraction of copper from chalcopyrite ore, the ore $\ce {Cu2S.Fe2S3}$ is heated to form $\ce {Cu2S}$ and $\ce {Fe2S}$. Then during smelting it reacts with $\ce {O2}$ to form $\ce {Cu2O}$ . Then it is written that $\ce {Cu2O}$ reacts with $\ce {FeS}$ to form $\ce {Cu2S}$.
