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

Smelting - Wikipedia
Electric phosphate smelting furnace in a TVA chemical plant (1942). Smelting is a process of applying heat and a chemical reducing agent to an ore to extract a desired base metal product. [1] It is a form of extractive metallurgy that is used to obtain many metals such as iron, copper, silver, tin, lead and zinc.Smelting uses heat and a chemical reducing agent to decompose the ore,
