This study investigates the current distribution along the sides of Soderberg aluminium electrolysis cells using a voltage probe to determine performance characteristics. The objective was to quantify the reduction in current density from the anode's working face to its surface. Experimental results demonstrated that current density diminished from 0.8 A cm-2 at the working face to a range of 0.15-0.28 A cm-2 near the bath surface. It was estimated that only 5%-10% of carbon dust in Soderberg cells emanated from the anode's side, with the majority generated at the working face. Notably, approximately 5% of the total anode consumption was attributed to side reactions, with about 3% resulting from air-burning above the bath level. The findings highlight the substantial implications of current distribution on anode efficiency and consumption rates, suggesting that management of current density could facilitate reductions in carbon emissions and enhance the overall sustainability of aluminium electrolysis processes.
