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
