The extraction of aluminium involves two steps that is, purification of bauxite by Baeyer's process and electrolysis of alumina 1 Purification of bauxite by Baeyer's process In the Baeyer's process, the bauxite ore is heated with concentrated NaOH solution under pressure (Aluminum is purified by leaching method)The alumina dissolves as sodium meta aluminate.

It is in the blast furnace that extraction of iron occurs The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag What happens in the Blast Furnace? The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal state.

The copper(II) ions in the chalcopyrite are reduced to copper(I) sulfide (which is reduced further to copper metal in the final stage) 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.
