Investigation of Electrolytic Bubble Behaviour in Aluminum Smelting Cell

A 1/4th scale low temperature electrolytic model of the Hall-Heroult cell was constructed to investigate the electrolytic bubble formation mechanism, coalescence and movement under the horizontal anode surface. Geometric and dynamic similarity between the model and real cell was maintained through using similarity criteria. A 0.28M CuSO4+20%H2SO4 solution was selected as an electrolyte where Cu was deposited at the cathode and O2 bubbles were …
