Iron Ore
Lowgrade ore is a term applied to ironrich rocks with cutoff grades in the range of 25�30% Fe. It was the main supply of iron ore for many centuries of the World's early history of production of iron. Since the 1950s North America's main supply has been lowgrade ore. The dominant economic iron mineral in lowgrade ore is magnetite.
