Aug 03, 2020 Aluminum has been manufactured from bauxite with the same basic steps since its invention in the 1880s, although its efficiency has been continuously increased since then. First the Bayer process is used to refine the bauxite into aluminum oxide (alumina), and then that is turned into aluminum with the Hall-Heroult smelting process.
