Oct 05, 2016 Hematite is the most important iron ore. The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron. It is of valuable composition, carries only 14 or 15% of iron, and is used more for its lime and magnesia as a flux than for its iron-content.

Jan 01, 2015 Oxidized iron ores are much more difficult to upgrade by magnetic separators, because their magnetic susceptibilities are only about 1% or less of that of magnetite. In oxidized iron ore separation, it is therefore important to create magnetic fields with high intensities and high gradients to achieve higher iron recoveries. 9.3.2.1.

Low-grade ore is a term applied to iron-rich rocks with cut-off grades in the range of 2530% 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.
