NATURAL RESOURCES SUSTAINABILITY: IRON ORE MINING

Although hematite possesses a higher ratio of oxygen (O/Fe = 1.5) than does magnetite (O/Fe = 1.33), hematite is more easily reducible than magnetite because magnetite is crystalline (is less reactive and displays a lower ability to reduce than hematite). Thus, the benefits achieved when pre-reducing iron ore must be introduced into the index.
