Pre-heating of alumina. Weight of rafts at different temperatures
It has been suggested that the alumina added to aluminium electrolysis cells should be pre-heated to obtain more rapid dissolution and thereby smoother operation. To investigate the effect of pre-heating, the formation of alumina "rafts" upon feeding a batch of alumina to the surface of mo...
Wetting Phenomena in Aluminium Electrolysis
Interfacial tension and wetting phenomena are important in all industrial processes, and the aluminium electrolysis is no exception. The present paper explains some of the basic principles related to interfaces, including the Young equation and principles for computing the shape of surfaces. An anal...

Effect of composition and temperature on current efficiency for aluminium electrolysis from cryolite-based molten alumina electrolytes
Gas anodes made of porous graphite for aluminium electrowinning
One of the major downsides of the current aluminium production process is the high CO2 emission. One alternative is to replace the consumable carbon anodes with inert anodes so that oxygen evolves instead of CO2. Also PFC emissions will be eliminated by using inert anodes. However, so far a sufficie...
