Processing High-Grade Concentrates from Challenging

2013-7-3  Siderite, that is iron carbonate, is naturally low-grade in Fe even if the mineral content in the ore may be high. Common processing started with calcination to drive off CO 2, followed by low-intensity magnetic separation as the FeCO 3 was more or less converted to magnetite, Fe 3 O 4. The processing sometimes had detrimental consequences ...

Iron Ore - Department for Energy and Mining

2021-11-15  Low-grade ore is a term applied to iron-rich rocks with cut-off grades in the range of 25�30% Fe. It was the main supply of iron ore for many centuries of the World's early history of production of iron. Since the 1950s North America's main supply has been low-grade ore. The dominant economic iron mineral in low-grade ore is magnetite.
