Wisconsin Geological & Natural History Survey » Mining: Iron
Types of iron ore Iron ore is present in a number of places and geologic settings within Wisconsin Iron ore can be defined on the basis of its iron content into low-grade ore (taconite), which commonly contains 25 to 35% iron, and high-grade ore, which contains 50 to 70% iron
Iron (chemical symbol Fe) is the second most common metal on Earth, and the most widely-used metalIt is element 26, a transition metal in Group 8Its symbol is Fe, from the Latin word for iron, ferrumIts atomic number is 26 and its mass number is 5585 It is used a lot because it is very strong and cheap Iron is the main ingredient used to make steel .
