Wisconsin Geological Natural History Survey Limonite

Description: Limonite is a general term for a mixture of fine-grained iron oxides, generally dominated by goethite, but also possibly containing hematite, lepidochrocite and other minerals. It forms from the weathering of other iron minerals, and may be precipitated by iron rich surface or ground water. Get price

Red Iron Oxide (Hematite)

Iron is rarely found as a free element, since it tends to oxidize easily; it is usually found in minerals such as magnetite, hematite, goethite, limonite, or siderite. Though pure iron is typically soft, the addition of carbon creates the alloy known as steel, which is significantly stronger. Get price

Hematite after Magnetite (#43)

As specimen #37 is a pseudomorph, this specimen is a pseudomorph of hematite after magnetite. All of the physical properties associated with hematite are in evidence except the shape of the crystals. Hematite crystallizes in a different crystal system than does magnetite, and its unit cell is not a cube, but a prism with a diamondshaped cross-section, so hematite crystals look very different Get price

Hydrogen Reduction of Hematite Ore Fines to Magnetite

Surplus coke oven gases (COGs) and low grade hematite ores are abundant in Shanxi, China. Our group proposes a new process that could simultaneously enrich CHsub4/sub from COG and produce separated magnetite from low grade hematite. In this work, low-temperature hydrogen reduction of hematite ore fines was performed in a fixed-bed reactor with a stirring apparatus, and a Get price

University of Minnesota's Mineral Pages: Hematite

Regardless of its setting, hematite is usually found with other iron-bearing minerals, especially magnetite, goethite and siderite. In Early Proterozoic (2.5 to 1.6 billion year ago) iron ore deposits, layers of hematite and other iron oxides alternate with bands of chert (microcrystalline quartz) to form distinctively layered deposits known as Banded Iron Formation.
