In this reduction reaction, oxygen is removed from the iron (III) oxide to leave behind iron. Generally, the extraction of metals and their isolation are based on three major procedures. The steps are: 1. Concentration of Ore. 2. Extraction of metal from concentrated ore and. 3. Purification of the metal.

Mild steel is iron containing up to about 0.25% of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things – nails, wire, car bodies, ship building, girders and bridges amongst others.

Reduction with carbon. Iron is extracted from its ore, haematite, by reduction with carbon. A mixture of crushed iron ore, coke (an almost pure form of carbon) and limestone is fed into the top of the blast furnace. The reaction is exothermic. The carbon dioxide reacts with coke to form carbon monoxide. The reaction is endothermic.

Preparation of Wrought Iron. This is done by heating cast iron with haematite (Fe 2 O 3) which oxidizes C to CO, S to SO 2, Si to SiO 2, P to P 4 O 10 and Mn to MnO. Fe 2 O 3 + 3C → 2Fe + 3CO. Where CO and SO 2 escape, manganous oxides (MnO) and Silica (SiO 2) combine to form slag. MnO + SiO 2 → MnSiO 3.

The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulfur in the chalcopyrite turns into sulfur dioxide gas. This is used to make sulfuric acid via the Contact Process. An overall equation for this series of steps is: [2CuFeS_2 + 2SiO_2 +4O_2 rightarrow Cu_2S + 2FeSiO_3 + 3SO_2 label{1} ]
