A fine, snowy white powder called Alumina (aluminum oxide) [1, 6]. Act III: The Lightning Strike (The Hall-Héroult Process)
The remaining clear liquid is cooled, causing white crystals to settle out [1, 6]. How Aluminium is made animation
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 fine, snowy white powder called Alumina (aluminum
The electricity rips the oxygen away from the aluminum. The oxygen bonds with the carbon rods and floats away as CO2, while the pure, heavy molten aluminum sinks to the bottom of the vat [1, 6]. Act IV: The Final Form The electricity rips the oxygen away from the aluminum
Our story begins in tropical regions, where a reddish-clay rock called is mined [1, 5]. It doesn’t look like metal at all; it’s a mix of aluminum compounds, silica, and iron rust [5, 6].
These crystals are baked in a rotary kiln at over 1,000°C [1, 6].
To start the animation, imagine giant excavators scooping this red earth into a massive grinding mill. The rock is crushed into a fine powder, ready for its first big chemical makeover [6]. Act II: The White Powder (The Bayer Process)
