Abstract. This article gives a brief overview of the history of modern aluminium production, which started with the invention of electrowinning of dissolved aluminium oxide in molten cryolite (Na 3 AlF 6 )-based electrolytes in 1886. All primary aluminium production is still based on the same principles, although numerous …
