Tips

• The aluminum production is a looping recipe both using and producing Water. To prevent the recycled Water from backing up and clogging the setup, Pipeline systems for fresh and recycled Water and connected Refinery setups should be separated.
  • For example: a setup utilizing 480 Bauxite/min producing 822.85 Aluminum Scrap/min consumes 685.71 m³ of Water/min but produces 137.14 m³/min of it at the end, which means that only 548.57 m³ of Water should be extracted. Therefore, there should be two setups for producing Alumina Solution, one solely from fresh Water (5.49 Refineries) and the other one solely from recycled Water (1.38). If underclocking is preferred over overclocking, there will be 8 Refineries in total. Alumina Solution from both sources is then mixed and processed in 2.29 Refineries into Scrap.
• The Silica produced as a byproduct does not suffice for Aluminum Ingot production (using the standard recipe), more of it has to be produced from Raw Quartz. It can be omitted with the Pure Aluminum Ingot alternate recipe, which however reduces ingot yield by 25%.

Trivia

• Alumina Solution is more or less a fictional fluid. The closest real-life fluid is sodium aluminate.
• The in-game refining process resembles the real-life refining process:
  • Real-life bauxite contains relatively high amounts of silicone and even small amounts of titanium.
  • It is crushed into a very fine powder and mixed with water and other chemicals, making alumina slurry.
  • The alumina is extracted via electrolysis.
  • Caustic soda (aka sodium hydroxide) is added to prevent the aluminum from reacting during the smelting process.
• Alumina is another name for aluminum oxide, AlO2.
