Abstract Scope |
The growing emphasis on sustainable steel production has made the management and recycling of Electric Arc Furnace (EAF) dust increasingly critical. EAF dust, a hazardous byproduct of steelmaking, contains valuable metals such as zinc and lead but is difficult to process efficiently. Current treatment methods are often energy-intensive and environmentally harmful. This study investigates a more sustainable alternative by analyzing the solid-state reduction of EAF dust using methane-hydrogen mixtures. A thermodynamic model, developed with HSC Chemistry® 7.1, was used to predict the equilibrium products of this reduction process. Given the stability of certain oxides in EAF dust, additives like lime were employed to aid in their reduction. The modeling results identified optimal conditions for maximizing metal recovery while minimizing environmental impact. |
