Developments in the physical separation of iron ore ...

2015-1-1  Magnetic separation is the most important method for upgrading low-grade iron ores to high-quality iron ore concentrates because of its high capacity and low operating cost. Iron ores are divided into two different groups according to their magnetic susceptibility, that is, strongly magnetic iron ore such as magnetite and weakly magnetic iron ores (oxidized iron ores) including martite, hematite,
