A study of reduction and magnetic separation of iron from

Abstract The removal of iron as magnetite from a high iron bauxite ore was investigated by carbothermal reduction and magnetic separation. Thermodynamic calculations using HSC Chemistry 6 1 were utilised to determine the equilibrium compositions of the reaction products as a function of temperature and carbon additions.Fote, a leading manufacturer of magnetic-separator machinery. Under equilibrium conditions, the formation of hercynite (FeAl2O4 ...

Recovery of Iron Values From Tailing Dumps Adopting

The studies on hydrocyclone and magnetic separation had indicated that an iron concentrate of 61 - 65 per cent Fe could be obtained by recovering 59 - 78 per cent of the iron values present in the slimes. Depending on the nature of the slimes the alumina and silica levels have been brought down to 2.5 and 1.0 per cent respectively.

Comprehensive reutilization of iron in iron ore tailings

Jun 23, 2020 A large number of iron ore tailings (IOTs) are produced in steel industry, posing threat to the environment during its storage and disposal. To effectively reutilize Fe in IOTs, we propose a comprehensive utilization scheme: (1) most Fe in IOTs is extracted by concentrated hydrochloric acid to form FeCl3 flocculants; (2) after separation from the FeCl3 flocculants, a small amount of Fe is ...

Principles of Magnetic Separation Minerallurgy

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.
