Extraction of Aluminium
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.

An Introduction to the Chemistry of Metal Extraction
An ore is any naturally-occurring source of a metal that you can economically extract the metal from. Aluminum, for example, is the most common metal in the Earth's crust, occurring in all sorts of minerals. However, it isn't economically worthwhile to extract it from most of these minerals. Instead, the usual ore of aluminum is bauxite - which ...

The Extraction of Copper
The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulfur in the chalcopyrite turns into sulfur dioxide gas. This is used to make sulfuric acid via the Contact Process. An overall equation for this series of steps is: [2CuFeS_2 + 2SiO_2 +4O_2 rightarrow Cu_2S + 2FeSiO_3 + 3SO_2 label{1} ]
