Abstract:
The rapid growth of electric arc furnace (EAF) steelmaking has led to a significant increase in zinc-bearing metallurgical dusts, which pose both an environmental hazard and a secondary resource opportunity. This research article analyzes recent methodologies published in Scopus-indexed journals regarding the extraction of zinc (Zn) from ferrous metallurgy dusts. Through a systematic review of pyrometallurgical and hydrometallurgical approaches, this study evaluates extraction efficiencies, process parameters, and limitations. Results indicate that while pyrometallurgical methods, particularly chlorinating roasting, achieve zinc recovery rates exceeding 98% by breaking down stable zinc ferrites, hydrometallurgical innovations using ammonium and alkaline lixiviants offer promising low-energy alternatives with recovery rates between 80-88%. The study concludes that hybrid approaches combining physical separation with selective leaching represent the optimal path for future industrial applications.
