| Abstract: | Experimental research on low temperature magnetic roasting—magnetic separation for Zinc-bearing dust in blast furnace was carried out in this paper.The result shows iron concentrate with high-grade can be effectively extracted from the dust adopting the technology of low temperature magnetic roasting—magnetic separation when the roasting temperature is about 900℃ and the roasting time is 30min.The roasted products should be cooled by means of water-cooling because it can effectively prevent oxidation.Thermodynamic study shows that the roasting temperature can be properly improved in order to enhance the reaction speed. |
