extraction of aluminium from bauxite wiki

Aluminium - Wikipedia

The production of aluminium starts with the extraction of bauxite rock from the ground. The bauxite is processed and transformed using the Bayer process into alumina, which is then processed using the Hall-Héroult process, resulting in the final aluminium metal.

Alumina Solution - Official Satisfactory Wiki

The in-game refinement process resembles the real-life refining processes, in which bauxite is refined to pure alumina by the Bayer process and then to aluminum metal by the Hall-Héroult process. Alumina is another name for aluminum oxide, Al 2 O 3. In real life, Alumina Solution is used both as a refining intermediate and as a polishing abrasive.
