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)
The aluminum in the rock dissolves into the liquid, while the unwanted "red mud" (iron and silica) sinks to the bottom and is filtered out [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].
These crystals are baked in a rotary kiln at over 1,000°C [1, 6].
The remaining clear liquid is cooled, causing white crystals to settle out [1, 6]. How Aluminium is made animation
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].
Massive carbon rods (anodes) are lowered into the vat, and a colossal electric current—hundreds of thousands of amperes—is surged through the liquid [1, 6].
