How aluminum is made
The difficulty of extracting aluminum from its natural compounds kept the metal rare for many years; half a century after its discovery, it was still as rare and valuable as silver. In 1886, two 22-year-old scientists independently developed a smelting process that made economical mass production of aluminum possible.

How Aluminum is Produced | Metallurgy for Dummies
How Aluminum is Produced. Aluminum manufacture is accomplished in two phases: the Bayer process of refining the bauxite ore to obtain aluminum oxide, and the Hall-Heroult process of smelting the aluminum oxide to release pure aluminum. Bauxite is the mineral form of aluminium. Aluminum compounds have proven useful for thousands of years.
