Low grade Iron Ore Beneficiation and the Process of
Sep 25, 2018In some places reduction roasting of the low grade hematite ore is done to convert it into magnetic ore before the application of the magnetic separation method for the ore beneficiation. Another method which can be employed is the use of a dense medium in a gassolid fluidized bed for the enrichment of iron ore.
