Determining Iron Grades of Ores or Concentrates

2020-2-18  Iron ores used in the steel industry must have some certain chemical properties including the amount of Fe(II), Fe(III), and the total Fe. In some geological studies, having an accurate level of Fe(II) and Fe(III) is essential for determining the petrology and mineralogy of an ore.[] Iron is found naturally in hybrid forms such as oxide, sulfide, carbonate, and silicate.
