This is a story of transformation—how a crumbly red rock from the earth becomes the sleek, silver metal in your soda can or smartphone. Act I: The Earth’s Rusty Treasure How Aluminium is made animation
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]. From red dirt to white powder, and from
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]. It is whisked away to a furnace where

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