Extraction of Aluminium (Aluminium Ore) - Hall-Heroults ...

2021-11-10  The Hall-Heroult process is widely used in the extraction of aluminium. In Hall-Heroults process, pure Al 2 O 3 is mixed with CaF 2 or Na 3 AlF 6. This results in lowering of the melting point of the mixture and increases its ability to conduct electricity. A steel vessel with the lining of carbon and graphite rods is used.

Recycling of Metals MATSE 81: Materials In Today's World

Aluminum is the most commonly recycled metal. Aluminum is used to make soft drink cans, aluminum foil, certain food cans, and even certain packaging materials. Aluminum is also used to make the outer bodies of some cars and airplanes due to the fact that it is less dense than steel. The extraction of aluminum from its ore is done by electrolysis.
