    Abstract:

    Red mud is the major solid waste produced in the process of alumina extraction. The red mud, assaying 50.60%Fe, 8.36%Al2O3, was developed to effectively beneficiate iron by the process of direct reduction-low intensity magnetic separation. The upgrading results show that the final iron concentrate, assaying 90.9wt%Fe, 0.95wt%Al2O3 and 95.5% metallization degree was obtained at an overall iron recovery of 95.8% under the following conditions: coal based reducing the red mud pellets containing 12% sodium containing complex additive at 1050 oC for 80 min, and finally magnetic separation of the reduced pellets by grinding up to 97.2% passing 0.074 mm at 0.1T field intensity.
