How Aluminium Is Made Animation Page

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].

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].

From red dirt to white powder, and from a lightning-bolt bath to a silver slab, the aluminum is now ready to be shaped into anything from a foil wrap to a jet engine. 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].

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 Massive carbon rods (anodes) are lowered into the

This is the most dramatic part of the animation. Alumina is very stable; you can’t just melt it with fire to get the metal out. You have to "shock" it [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) Our story begins in tropical regions, where a

The crushed bauxite enters a high-pressure "pressure cooker" filled with hot caustic soda [1, 6].
