“…As a result, we used multiphase computational fluid dynamics to conduct numerical simulations to confirm the effects of hydrodynamic factors. Although a detailed explanation is omitted here, the solution method was based on the previous report by the authors, 52 and each physical property value was derived from previously published literature. 51,[53][54][55][56] For simplicity, the Fe-C rich phase and the Cu-rich phase were combined in a volume ratio of 1:1 in the bottom of an alumina container, and the molten slag phase was added.…”

This study focused on the use of molten oxide electrolysis (MOE) as a low-cost, clean, continuous separation method suitable for incorporation into actual steelmaking processes. We discussed interfacial behavior from molten iron to slag by anodic polarization of the copper-containing carbon-saturated molten iron (metal phase)–molten oxide (slag phase) interface and investigate the operating mechanism of MOE. The basic constant potential electrolysis between the metal phase (Fe-10 wt% Cu-5.0 wt% C) and slag phase (27 wt% CaO-27 wt% SiO2-45 wt% Al2O3-1.0 wt% CaS) by maintaining 1–2 V vs. Pt at 1773 K in an Ar atmosphere is described. When polarized, a high concentration of dispersed Cu-rich phase was detected locally near the metal–slag interface but not in the phase center of the metal. At the metal–slag interface, the energies of the Fe-rich and Cu-rich phase–slag interfaces decreased due to electric capillarity, and the Cu-rich phase distributed near the interface.
