Iron Recovery from Red Mud by Reduction Roasting-Magnetic Separation
Abstract. This work provided an effective method for comprehensive utilization of red mud, which mainly focused on the first step of recovering iron from a high iron content red mud by reduction roasting-magnetic separation. During the reduction, iron oxides were reduced to metallic iron with the aid of sodium sulfate and sodium carbonate.

Design of microfluidic channels for magnetic separation of malaria
Magnetic separation of parasitized, malaria-infected red blood cells within a parallel-plate system was simulated using a CFD-DEM (Eulerian–Lagrangian) approach. The plasma was treated as a Newtonian fluid (as the Eulerian phase), and the RBCs were treated as soft spheres (as the Lagrangian phase) influenced by drag, collisions with …

Recovery of alumina from magnetic separation tailings of red mud has been investigated by Na2CO3 solution leaching. X-ray diffraction (XRD) results show that most of the alumina is present as 12CaO·7Al2O3 and CaO·Al2O3 in the magnetic separation tailings. The shrinking core model was employed to describe the leaching kinetics. The …

Recycling of iron from red mud by magnetic separation after co-roasting
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, …
