| Abstract Scope |
Biomass-assisted reduction offers a low-carbon route for recovering valuable metals from Zn/Fe-bearing solid wastes such as electric arc furnace dust. In this study, the reduction behavior and kinetics of Zn/Fe-containing wastes using biomass-derived reductants were investigated under controlled thermal conditions. The effects of temperature, reaction time, biomass addition, and gas evolution on phase transformation, zinc volatilization, and iron oxide reduction were systematically evaluated. Kinetic analysis was performed using model-fitting and apparent activation energy calculations to clarify the rate-controlling mechanisms during reduction. The results indicate that biomass promotes the generation of CO and reactive carbon, enhancing zinc oxide reduction and iron metallization while lowering the required reaction temperature. The reduction process is strongly temperature-dependent and may involve a transition from chemical-reaction control to diffusion-related control at higher conversion. This work provides kinetic insight into sustainable treatment of Zn/Fe-bearing metallurgical wastes and supports biomass-based circular utilization strategies. |
