Pyrochemical reprocessing is a non-aqueous method for reprocessing spent metallic fuels, with electrorefining being a critical step in this process. This study aims to understand the mechanisms involved in copper electrorefining using the Ambient Temperature ElectroRefiner (ATER) facility. The research includes laboratory experiments where electrolysis of copper is performed in acidified copper sulphate electrolyte, alongside numerical simulations of copper electrodeposition utilizing the secondary electrodeposition module of COMSOL. The simulations have been validated against experimental results, revealing insights into current densities essential for effective electrodeposition. This paper details the modeling conducted for pilot plant scale operations, presenting current density estimates for different cathode geometries and the requisite time for batch copper deposition. The findings indicate that there is a close correlation between theoretical predictions of current densities and experimental outcomes, providing a comprehensive understanding of the electrorefining process necessary for efficient metal recovery in industrial applications.
