How is Aluminium Extracted from Bauxite Ore
The process to extract the aluminium from its ore is a seemingly complex and time consuming one, and it goes as follows: Bauxite Mining The first step in the process is to mine the bauxite from the earth, mostly from underground deposits (the largest ones can be found in Southern Europe and Hungary). The bauxite is blasted loose and washed to remove any excess clay.

Aluminium Aluminium is the most plentiful metallic element in the Earth's crust. Combined with oxygen and hydrogen, it forms bauxite, the ore most commonly mined in order to obtain aluminium. Metallic aluminium was first isolated in 1829 from aluminium chloride, but it was not commercially produced until 1886. Aluminium is a silverywhite, tough, but lightweight metal.
