The most commonly used iron ores are haematite (US: hematite), Fe2O3, and magnetite, Fe3O4.The two equations for the reduction of the ore on this page are for haematite.In the fairly unlikely event that you need the equations for magnetite, they aren't difficult to work out for yourself.The heat source
The air blown into the bottom of the furnace is heated using the hot waste gases from the top.This reaction is the main source of heat in the furnace.Notice that at these temperatures, the other product of the reaction is carbon monoxide, not carbon dioxide.The limestone is added to convert this into slag which melts and runs to the bottom.The heat of the furnace decomposes the limestone to give calcium oxide.This is an endothermic reaction, absorbing heat from the furnace.It is therefore important not to add too much limestone because it would otherwise cool the furnace.Calcium oxide is a basic oxide and reacts with acidic oxides such as silicon dioxide present in the rock.Cast iron
The molten iron from the bottom of the furnace can be used as cast iron.If you hit it hard, it tends to shatter rather than bend or dent.For example, although guttering and drainpipes were once made of cast iron, apart from special old buildings, it is now quite hard to find any which aren't made of plastic!Impurities in the iron from the Blast Furnace include carbon, sulphur, phosphorus and silicon.Removal of carbon etc
The still impure molten iron is mixed with scrap iron (from recycling) and oxygen is blown on to the mixture.The oxygen reacts with the remaining impurities to form various oxides.Since this is a gas it removes itself from the iron!Elements like phosphorus and silicon react with the oxygen to form acidic oxides.They react to form compounds such as calcium silicate or calcium phosphate which form a slag on top of the iron.Types of iron and steel
Cast iron has already been mentioned above.Wrought iron is quite soft and easily worked and has little structural strength.It was once used to make decorative gates and railings, but these days mild steel is normally used instead.Mild steel
Mild steel is iron containing up to about 0.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.High carbon steel is used for cutting tools and masonry nails (nails designed to be driven into concrete blocks or brickwork without bending).Special steels
These are iron alloyed with other metals.This is deliberately brief because a lot of it is just common sense, and you will probably already have met it in detail in earlier chemistry courses, in geography, in general studies, or wherever.Noise and air pollution (greenhouse effect, acid rain) involved in these operations.Loss of landscape due to the size of the chemical plant needed.Disposal of slag, some of which is just dumped.Saving of raw materials and energy by not having to first extract the iron from the ore.Not having to find space to dump the unwanted iron if it wasn't recycled.Offsetting these to a minor extent) Energy and pollution costs in collecting and transporting the recycled iron to the steel works.Where would you like to go now?To the Metal Extraction menu .
