Magnetite - American Chemical Society
Magnetite is a mineral whose primary component is an iron oxide that contains equal amounts of iron (II) and iron (III). Its empirical formula is Fe 3 O 4, and it is often expressed as iron (II,III) oxide. In the past, it has been called ferrous–ferric oxide and triiron tetraoxide. Magnetite is found in igneous, metamorphic, and sedimentary ...

Magnetite - Wikipedia
Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 2+ Fe 3+ 2 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. With the exception of extremely rare native iron deposits, it is the most magnetic of all the naturally occurring minerals on Earth.

Processing. Sino Iron's processing plant is where we transform the magnetite ore into high quality, premium magnetite concentrate. This is the heart of our operation at Sino Iron. Before the ore arrives at the processing plant via the conveyor, it's already been reduced down at the in-pit crushers to roughly the size of house bricks.

Iron processing - Ores | Britannica
Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is red; magnetite (Fe3O4), which is black ...
