Solution:

During the extraction of copper, iron is present in the ore as impurity (FeS). The ore together with a little coke and silica is smelted; FeS present as impurity in the ore is oxidized to iron oxide, which then reacts with silica to form fusible ferrous silicate which is removed as slag. $2 FeS + 3 O_{2} \to 2 FeO + 2 SO_{2} ↑$
