| Abstract Scope |
This study explored the hydrogen reduction of sulfur-containing iron ore to produce high-quality direct reduced iron (DRI), offering a potential low-carbon and environmentally friendly alternative for DRI production. The research highlighted that hydrogen (H2) performed well in both the reduction and the desulfurization of sulfur-containing iron ores. By optimizing roasting parameters, the optimal conditions were determined to be the roasting temperature of 1000 °C, dwell time of 90 min, and H2 concentration of 30%. Experimental results revealed that the metallic iron yield and sulfur removal percentage of the reduced product were 93.3% and 95.9%, respectively. Furthermore, high-quality DRI was successfully obtained via conventional magnetic separation, meeting industrial application standards. This method not only significantly improved the reduction of sulfur-containing iron ores but also drastically lowered the sulfur content in the DRI, presenting a promising route for the comprehensive utilization of sulfur-containing iron ores in China. |
