Magnetite (Fe3O4), like hematite (Fe2O3), is a form of iron ore. It is a benign and highly magnetic substance used primarily in steel manufacturing and coal washing. Magnetite occurs in nearly all igneous and metamorphic rocks and usually only in small particles or in a solution with other minerals.

The most common ironcontaining ore is haematite, but iron is found widely distributed in other minerals such as magnetite and taconite. Commercially, iron is produced in a blast furnace by heating haematite or magnetite with coke (carbon) and limestone (calcium carbonate).

Magnetite Ore, Magnetite Iron Ore, Iron Ore Mining Process Magnetite ore is a ferromagnetic material, with the chemical formula Fe3O4, and is one of several types of iron is a ubiquitous mineral in many parts of the world, including Australia, the USA, Canada, South Africa, Mozambique and many other countries across most of the world's ...
Discover Magnetite Processing. The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe3O4) which when processed produces a magnetite concentrate with a magnetic content in excess of 96% magnetics. Further magnetic separation and milling produces even higher iron levels in the magnetite concentrate.
Magnetite. Magnetite, also called lodestone, or magnetic iron ore, iron oxide mineral (FeFe 2O4, or Fe 3 O 4) that is the chief member of one of the series of the spinel ( ) group. Minerals in this series form black to brownish, metallic, moderately hard octahedrons and masses in igneous and metamorphic rocks and in granite pegmatites,...
Magnetite ore, long the leading source of domestic iron supply in North America, Europe and China, is now increasingly relevant across the globe. The perception that magnetite ore is an inferior substitute to hematite ore is now firmly changing.
Magnetite is an important ore of iron. Its perfect crystals are also famous among mineral collectors. This mineral is of scientific interest because of its special magnetic properties. ... Magnetite / Black Iron Oxide (Fe304) Powder Military Specification Number:MILI275B.
Magnetite is an important ore of iron. Well formed crystals are popular among mineral collectors, and the magnetic Lodestone variety is frequently sold in hobby shops to amateur collectors. Magnetite is also of significant interest to the science community due to its strong magnetic properties.
Briquetting. The ore consists of magnetite in a gangue of feldspar with a little quartz and apatite. The ore is mined in open quarries and contains lumps up to 5 tons in weight. It is loaded by steam shovels and dumped on skips holding tons each, which are hauled to the mill on cars by locomotive.
Hematite. Hematite is colored black to steel or silvergray, brown to reddish brown, or red. It is mined as the main ore of iron. Varieties include kidney ore, martite ( pseudomorphs after magnetite ), iron rose and specularite (specular hematite). While the forms of hematite vary, they all have a rustred streak.

The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe 3 O 4 ). Magnetite ore requires complex processing to separate magnetite minerals from other minerals in the ore to produce an almost pure magnetite concentrate with an iron content of between 68% Fe and 70% Fe that is highly sought after by steel makers.
JacobsiteMagnetite Series. MagnesioferriteMagnetite Series. Magnetite is an important iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007).
