How Aluminium Is Made Animation -

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 crushed bauxite enters a high-pressure "pressure cooker" filled with hot caustic soda [1, 6]. How Aluminium is made animation

The remaining clear liquid is cooled, causing white crystals to settle out [1, 6]. To start the animation

These crystals are baked in a rotary kiln at over 1,000°C [1, 6].
