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% …

These work well in removing ferrous tramp but not fine para-magnetic particles. High intensity magnetic separators focus on the separation of very fine particles that are para-magnetic. Controlled current is passed through an electromagnetic coil, which creates a magnetic field. This magnetises the yoke and finally the matrix ring.
