Inside the sprawling plant, heat and pressure are harnessed to transform bauxite — a reddish rock mined oceans away — into alumina, the main raw material needed to produce aluminum. Strong and resistant to corrosion, aluminum is vital for manufacturing military hardware like missiles, drones, and aircraft.
