Hematite: A primary ore of iron and a pigment mineral

Hematite is one of the most abundant minerals on Earth's surface and in the shallow crust. It is an iron oxide with a chemical composition of Fe 2 O 3. It is a common rock-forming mineral found in sedimentary, metamorphic, and igneous rocks at locations throughout the world. ADVERTISEMENT Hematite is the most important ore of iron.

hematite | Definition, Uses, & Facts | Britannica

hematite, also spelled haematite, heavy and relatively hard oxide mineral, ferric oxide (Fe 2 O 3), that constitutes the most important iron ore because of its high iron content (70 percent) and its abundance. Its name is derived from the Greek word for "blood," in allusion to its red colour. Many of the various forms of hematite have separate names. The steel-gray crystals and coarse ...

Iron ore - Wikipedia

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...

Hematite: The mineral hematite information and pictures

The Mineral hematite Hematite is one of the most common minerals. The color of most red and brown rock, such as sandstone, is caused by small amounts of Hematite. It is also be responsible for the red color of many minerals. Non-crystalline forms of Hematite may be transformation s of the mineral Limonite that lost water, possibly due to heat.

Iron Ore | Geoscience Australia

Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). Hematite is an iron oxide mineral. It is non-magnetic and has colour variations ranging from steel silver to reddish brown. Pure hematite contains 69.9% Fe by molecular weight.

tilden - Michigan State University

Concentrating Hematite When processing hematite, Tilden must use a flotation system specially developed for the mine's fine-grained ore, rather than by magnetic separation. The finely ground mineral particles are conditioned by adding caustic soda and a dispersant in the grinding process.

The dominating rocks of the super group are various types of mica shists, dolomitic marbles, limestones, amphibolites and quartzites. The iron ore contains an average of 33% iron in the forms of the oxide minerals hematite and magnetite. Hematite makes up 97.5% to 98% of the iron oxides. Magnetite corresponds to 2.5% to 2.0% in the Kvannevann mine.
