Not All Iron Is Magnetic (Magnetic Elements)
Jul 03, 2019 Iron is ferromagnetic (attracted to magnets), but only within a certain temperature range and other specific conditions. Iron is magnetic in its α form. The α form occurs below a special temperature called the Curie point, which is 770 C. Iron is paramagnetic above this temperature and only weakly attracted to a magnetic field.Read More

How Is Iron Extracted From Iron Ore
The iron ore itself is not pure ore. It is also contaminated with a variety of rock, which will not necessarily melt at blast furnace temperatures and therefore could clog it up. For this reason, limestone, or calcium carbonate, is added to the initial furnace charge. The hot furnace reacts with the limestone to give calcium oxide. CaCO3 ...Read More
