NATURAL RESOURCES SUSTAINABILITY: IRON ORE …

The effects of selecting an appropriate iron ore are relevant when the ore is reduced in a blast furnace. 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).

While the iron ore price was expected to decline as additional supply came on line, the size of the fall has been larger than most forecasters anticipated.
