| Abstract: | This paper mainly discusses the magnetic separation technology of extracting iron ore concentrate from red mud under the condition of high-temperature roasting.Choosing red mud containing Fe2O3 as raw materials and coal fines as solid reductant,mixing them at different percentage and kneading.Then reducing roasting pellets under the condition of high-temperature.At last,by magnetic separation,we can obtain ore concentrates and assaying them to attain the optimum technological parameters. |
