how is aluminum extracted from its ore
About Aluminium Tomago
About Aluminium Aluminium is the most plentiful metal in the earth's crust. It is found in the form of aluminium oxide in an ore called bauxite. Alumina and bauxite are the two main raw materials in the aluminium making process. Aluminium is obtained by the electrolysis of alumina which extracts pure aluminium metal from alumina.

Copper Mining and Extraction: Sulfide Ores
Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid.

Aluminum | Minerals Education Coalition
Aluminum is the most abundant metal element in the Earth's crust. Bauxite ore is the main source of aluminum and contains the aluminum minerals gibbsite, boehmite, and diaspore. Aluminum is used in the United States in packaging, transportation, and building. Because it is a mixture of minerals, bauxite itself is a rock, not a mineral.
Extraction of Aluminium
Extraction of aluminium. Aluminium is extracted from it's ore by electrolysis. The electrolyte has to be molten ore, if a solution was used (as in the extraction of copper) hydrogen gas would be produced instead of the pure metal. The next problem lies in that aluminium ore, bauxite, has a very high melting point over 2000 degrees Celsius!

Aluminium Wikipedia
The chief ore of aluminium is bauxite. Aluminium metal is highly reactive, such that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals. Aluminium is remarkable for its low density and its ability to resist corrosion through the phenomenon of passivation.
