Roasting removes chemically bound water,turns nonoxide ores into iron oxide, and prepares the ore for crushing. Most iron ores fall into two broad categories: A) Ores that need to be roasted in order to be usable in the bloomery furnace. B) Ores that may still benefit from roasting, although it might not be completely necessary.
