Low-grade ore. Low-grade ore is a term applied to iron-rich rocks with cut-off 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 low-grade ore. The dominant economic iron mineral in low-grade ore is

High-grade ore from a few Midwestern mines remained too expensive to transport and mining low-grade ore proved economically unfeasible – leaving the eastern steel and iron industries faltering. In the iron ore shortage, Edison saw a way to economize the mining of low-grade ore with his electromagnetic ore separator
