Physical separation of iron ore: magnetic separation
It is therefore easier to upgrade specularite using magnetic separation, compared with hematite. In contrast, limonite is the least susceptible to magnetic fields and therefore most difficult to recover using magnetic separation. Siderite contains only 48.2% Fe and hence it is impossible to achieve an acceptable Fe grade for siderite concentrates.
