Answer to Question #89936 in Inorganic Chemistry for tania

Question

Using the properties of the substances involved, compare the method of commercial producing of aluminium from bauxite with the production of iron from iron ore.

Answer 1

At the main commercial aluminium production method bauxite ore is first digested by NaOH at moderate hydrothermal conditions, followed by aluminium hydroxide precipitation. Calcination of the hydroxide to alumina yields a high purity alumina feedstock for aluminum production.

The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace.
