The Aluminum Smelting Industry HARBOR Aluminum
The Hall-Héroult process enabled the mass production of aluminum. In 1888, Hall founded the first industrial smelting operation, and global production has grown ever since. Aluminum Smelting Today. Aluminum is extracted from bauxite (sedimentary rock) during a two-step smelting process. First, the Bayer process separates alumina from bauxite. Also known as aluminum oxide, alumina then undergoes the Hall-Héroult process, producing pure aluminum.
