- Blast furnace dust and electric arc furnace dust are two typical solid wastes in iron and steel industry. In order to overcome the shortcomings of traditional processes, such as low metal recovery efficiency and high secondary pollution, microwave energy was applied in this study to intensify the self-reduction of core-shell BF dust-EAF dust composite pellets based on impedance matching for realizing highly efficient migration and separation of iron, zinc, and lead. By reducing the composite pellets in microwave field, it was found that under the optimal conditions of proportion of EAF dust in shell to all EAF dust in the pellet of 20%, reduction temperature of 1000 degrees C, and dwell time of 15 min, metallized pellets with the total iron content of 68.73 wt %, iron metallization degree of 95.87%, zinc removal percentage of 88.78%, lead removal percentage of 94.38%, and compressive strength of 190.4 N/p were obtained.
