12.5.1.2 Iron Production - Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel. Iron oxides, coke and fluxes react with the

Modern blast furnaces produce approximately 10,000 tonnes of iron per day The process is demonstrated and explained below: Diagram showing the carbon extraction of iron The raw materials: iron ore (hematite), coke (an impure form of carbon), and limestone are added into the top of the blast furnace Hot air is blown into the bottom Zone 1:
The arrival of blast furnaces, however, opened up an alternative manufacturing route; this involved converting cast iron to wrought iron by a process known as fining.

The blast furnace appeared in Europe in the 15th century when it was realized that cast iron could be used to make one-piece guns with good pressure-retaining properties, but whether its introduction was due to Chinese influence or was an independent development is unknown. At first, the differences between a blast furnace and a Stückofen were slight.
Extraction and Processing Industries THE METAL Hot metal (blast-furnace iron). Most blast furnaces are linked to a basic oxygen steel plant, for which the hot metal typically contains 4 to 4.5 percent carbon, 0.6 to 0.8 percent silicon, 0.03 percent sulfur, 0.7 to 0.8 percent manganese, and 0.15 percent phosphorus.

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.
