Red mud is a hazardous waste of alumina production. Currently, the total accumulated amount of red mud is over 4 billion tons. The promising method of red mud processing is carbothermic reduction of iron at 1000–1400 °C into metallic form followed by magnetic separation. In this study, the mechanism of carbothermic solid-phase reduction of red mud was investigated.

A recycling process of iron from red mud by magnetic separation is proposed, in which iron oxide (Fe 2 O 3) in red mud transforms to magnetite (Fe 3 O 4) by anaerobic co-roasting with pyrite (FeS 2).TG-DTA and XRD results showed that hematite was reduced to magnetite by the thermo-decomposed compounds (iron monosulfide, pyrrhotite and element sulfur) of pyrite.

Figure : Schematic representation of forces acting upon a particle (Svoboda et aI., 2003) The principles of magnetic separation are such that when particles of different magnetic susceptibility are placed in a magnetic field, they tend to disrupt the direction or the flow of the magnetic field and at the same time lead to the particles being magnetically induced.

The shrinking core model was employed to describe the leaching kinetics.
