The crushed bauxite enters a high-pressure "pressure cooker" filled with hot caustic soda [1, 6].
The white powder is dissolved in a giant steel vat filled with molten cryolite (a mineral that helps it melt at a lower temperature) [1, 6].
A giant "vacuum" ladle siphons the liquid silver from the bottom of the pot [1]. It is whisked away to a furnace where it's purified and mixed with other metals to make it stronger [1, 6]. Finally, it is poured into molds to create massive blocks called , or rolled into thin sheets [1, 6].
A fine, snowy white powder called Alumina (aluminum oxide) [1, 6]. Act III: The Lightning Strike (The Hall-Héroult Process)
These crystals are baked in a rotary kiln at over 1,000°C [1, 6].
