Aluminum: Will O' the Wisp? | The Grantville Gazette

What is much more difficult is producing aluminum, and its alloys, from scratch. The process which made it possible to produce reasonably pure (over 99%) aluminum at a reasonable cost was the Hall-Heroult smelting process (1886), involving the electrolytic reduction of aluminum oxide (alumina) to the metal.
