Mar 01, 2014  The iron ores are actinolite–magnetite quartzite, magnetite actinolitite, actinolite magnetitite, magnetite dolomite, and magnetite talc (schist), among which, magnetite quartzite is the major type. Most of the iron ores are low-grade ores with TFe from 25% to 35%. Part of actinolite magnetitite is high-grade iron ore with TFe ≥ 50%.

Magnetite - Wikipedia

Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of ...

Origins of chromite and magnetite in sedimentary rocks ...

Samples in the MT group contain quartz, magnetite, siderite, ankerite, chlorite, biotite and chromite. The grain size of magnetite is much larger (20-150 μm) than that of hematite in the HM group. The magnetite is interpreted as a secondary mineral transformed from hematite during early diagenesis.
