How aluminium is produced - All About Aluminium

So before being used in aluminium production, alumina is first used to treat the gases emitted during the earlier production of aluminium. So it's a closed loop, in a sense. The aluminium reduction process requires huge amounts of electric power, so it's important to use renewable energy sources that don't contaminate the environment.
