In the secondary steelmaking process, scrap from various sources is melted in an electric arc furnace (EAF), producing dust containing valuable metals such as zinc, iron, copper, and nickel. Despite extensive research, both the complex composition and metal speciation of the dust have impeded process development. Current recycling processes for EAF dust are primarily pyrometallurgical, relying on carbothermic reduction with solid coal in a rotary kiln to separate and recover zinc and iron in oxide form. To reduce carbon dioxide emissions in EAF dust recycling, this study proposes using hydrogen as the reducing agent. The study employed thermogravimetric analysis (TGA) to investigate the hydrogen reduction of EAF dust. Non-isothermal experiments were conducted at heating rates of 5 °C/min in hydrogen within the temperature range from room temperature to 1000 °C. Nucleation (two-dimensional) at 540–640 °C with an Ea of 39.4 kJ/mol and phase boundary control at 650–750 °C with an Ea of 108.5 kJ/mol, best describe EAF dust reduction.
