Effect of composition and temperature on current efficiency for aluminium electrolysis from cryolite-based molten alumina electrolytes
Morishige, Taiki; Haarberg, Geir Martin; Gudbrandsen, Henrik; Skybakmoen, Egil; Solheim, Asbjørn; Takenaka, Toshihide (Peer reviewed; Journal article, 2017)The current efficiency (CE) for aluminium electrolysis in modern cells can be as high as 96 %. The main reason for loss in current efficiency is the so-called back reaction between dissolved metal and the anode product of ... -
Mass- and Heat Transfer during Dissolution of Alumina
Solheim, Asbjørn; Skybakmoen, Egil (The Minerals, Metals & Materials Series;2367-1181, Chapter; Peer reviewed, 2020)Dissolution of alumina in industrial aluminium cells is a complicated process, not least because it involves formation of agglomerates, and it involves mass- and heat transfer phenomena taking place simultaneously. In the ... -
Separation of Aluminum from More Noble Elements in an Electrolysis Cell with Side-by-Side Geometry
Solheim, Asbjørn; Kjos, Ole Sigmund; Skybakmoen, Egil; Gudbrandsen, Henrik (Peer reviewed; Journal article, 2021)Currently, recycled metal is diluted with primary metal to keep the concentration of alloying elements within specification. This will be more difficult in the future, when a larger proportion of the metal is made from ...
