Hematite, also spelled as haematite, is the mineral form of iron(III) oxide (Fe 2 O 3), one of several iron oxides. It is the oldest known iron oxide mineral that has ever formed on earth, and is widespread in rocks and soils. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.
Chemical phase method is used to test the iron distribution of the Brazilian hematite concentrate, according to the chemical solvent solubility and dissolution rate differences of every mineral or compound, the method of selective dissolution is used, the content of ferritic in various minerals or compounds are measured respectively, the results are shown in Table 2.
