Which of the ores mentioned in Table 6.1 can be concentrated by magnetic separation method?
The ore can be concentrated by the process of magnetic separation, only if either the ore or the gangue can be attracted in presence of magnetic field. In table 6.1, the ores of iron such as haematite (Fe2O3), magnetite (Fe3O4), siderite (FeCO3), and iron pyrite (FeS2) can be separated by the process of magnetic separation.
