Bauxite is the start of the aluminum chain, one of the most complex in the game. It is refined into alumina solution, then aluminum scrap, then aluminum ingots, a multi-step process that also produces silica and water byproducts.

The Aluminum Puzzle

Managing the fluid byproducts of the aluminum chain is a signature late-game challenge. It runs through the Refinery and feeds heat sinks and alclad sheets.
