Prereduction and magnetic separation of low grade manganese ore
In this study, ferruginous low-grade manganese ore was prereduced by CO, which converted iron oxide to Fe3O4 while manganese oxide was reduced to MnO. Then, the iron-rich component was collected by magnetic separation. The effects of sample particle size and various other reduction parameters on the efficiency of magnetic separation were studied.

The magnetic difference of the generated phase is also critical for the separation of manganese ferrites. To assess the magnetism and HV hardness of the two main phases during the grinding-magnetic separation process, pure manganese ferrites (MnFe 2 O 4) and pure silicate (Mn 0.5 Fe 0.5) 2 SiO 4) were synthesized and tested.

Explain the principle of magnetic separation.
Definition: The process of separating the solid-solid mixture by using a magnet is called magnetic separation. Principle: The mixture containing magnetic and non-magnetic components is separated by this method. Usually it is applicable to solid solid mixture. The magnet is moved over the mixture, close to the components of the mixture.
