Mineral processing - Concentration, Separation, Flotation: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density …

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), …
