  • CHAPTER-5 GEOCHEMISTRY OF IRON ORES

    MINERAL CHEMISTRY OF IRON ORES Hematite, magnetite, martite are the major iron bearing minerals in the iron ore. Secondary goethite is also an intricately associated major phase. The ores of magmatic types are often associated with ulvospinel and ilmenite as exsolution lamellae (Fig.-6E), and rutile as alteration product within magnetite.
