Not All Iron Is Magnetic (Magnetic Elements)

2019-7-3  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. Magnetic materials consist of atoms with partially-filled electron shells. So, most magnetic materials are metals. Other magnetic

Types of Iron Ore: Hematite vs. Magnetite_SMM

The deposit was discovered in 1844 and ore was first mined there in 1848, as per the State of Michigan’s website. Among the four types of iron ore deposits found in this area are magnetite and hematite ore. In Minnesota, magnetite iron ore is mined mainly in the Mesabi iron range, one of the four ranges that make up the Iron Range of Minnesota.

2015-1-1  Iron ore minerals. Based on the magnetic susceptibility values in Table 9.1, iron ore can be divided into two groups, namely, strongly magnetic iron ores, that is, magnetite (72.4% Fe), and weakly magnetic iron ores (oxidized iron ores), that is, martite (70.0% Fe), hematite (70.0% Fe), specularite (70.0% Fe), limonite (57.14–59.89% Fe), and
