Iron Ore: From Mining to Processing to Dust Control
Iron ore is a rock or mineral from which metallic iron can be extracted economically. It constitutes 5% of the earth’s crust. Viable forms of ore contain between 25% and 60% iron. Ore greater than 60% iron is known as natural ore or direct shipping ore, meaning it can be fed directly into iron-making blast furnaces.
