The Hall–Héroult process is the major industrial process for smelting aluminium. It involves dissolving aluminium oxide (alumina) (obtained most often from bauxite, aluminium''s chief ore, through the Bayer process) in molten cryolite, and electrolysing the molten salt bath, typically in a purpose-built cell. The Hall–Héroult process

Technology Innovation in Aluminum Products
The hydraulic-extrusion press dates to the early 19th century, well before the Hall-Héroult process for making aluminum. During the 1800s, the process was proven for lead and copper products. Although attempts by J.W. Hoopes of Alcoa in 1902–1904 to produce conductor wire by a vertical-extrusion process were unsuccessful, 15 his experiences led the way for extrusion to be used for other
