The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce ironIII oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.
This page looks at the various factors which influence the choice of method for extracting metals from their ores, including reduction by carbon, reduction by a reactive metal like sodium or magnesium, and by electrolysis. Details for the extraction of aluminium, copper, iron and titanium are given in separate pages in this section.

Methods of extraction Many metals are found in the Earth's crust as ores. An ore is usuallypound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more

An ore is a mineral that contains enough metal to make it worth extracting the metal. Carbon can be used to extract metals from some metal oxides. A metal can either be reduced or oxidised in a reaction. Reduction occurs when a metal inpound loses oxygen, to form the elemental metal. Oxidation occurs when a metal or carbon gains oxygen, to form anpound. Ideas
