Physical separation of iron ore: magnetic separation
9.2.2.1. Iron minerals. Based on the magnetic susceptibility values in Table 9.1, iron minerals can be divided into two groups, namely strong magnetic minerals, that is, magnetite (72.4% Fe), and weakly magnetic minerals, that is, martite (70.0% Fe), hematite (70.0% Fe), specularite (70.0% Fe), limonite (57.14–59.89% Fe), and siderite (48.2% …

Magnetite
Magnetite is a remarkable material with unusual properties and diverse applications. Probably the best-known example is magnetite iron ore used for steel production, which consumes millions of tons per year. Another lesser-known use is in water purification, where very-high-purity magnetite is used as a feedstock to produce iron-based chemicals.
