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.

The opposite of saving energy is wasting it. Toss an aluminum can into the trash instead of recycling it, and the energy required to replace that discarded resource with new aluminum from bauxite ore is enough to keep a 100watt incandescent light bulb burning for five hours or to power the average laptop computer for 11 hours, according to the Container Recycling Institute.
