The reactivity series shows metals in order of reactivity. The reactivity of a metal is related to its tendency to form positive ions. Iron and aluminium are extracted from their ores in various ways.
The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) 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.
Bauxite ore is a mixture of hydrated aluminium oxides and compounds of other elements such as iron. The aluminium compounds in the bauxite may be present as gibbsite 2(Al(OH) 3), böhmite (γ-AlO(OH)) or diaspore (α-AlO(OH)); the different forms of the aluminium component and the impurities dictate the extraction conditions. Aluminum oxides and hydroxides are amphoteric, meaning that they are ...
