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% …
