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