Extraction of Aluminium (Aluminium Ore) - Hall-Heroults Process & Uses ...

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 the melting point of the mixture and increases its ability to conduct electricity. A steel vessel with a lining of carbon and graphite rods is used.

How is uranium made into nuclear fuel?

Water injected with oxygen (or an alkali, acid or other oxidizing solution) is circulated through the uranium ore, extracting the uranium. The uranium solution is then pumped to the surface. The uranium solution from the mines is then separated, filtered and dried to produce uranium oxide concentrate, often referred to as 'yellowcake'.
