Limonite is an iron ore consisting of a mixture of hydrated iron(III) oxide-hydroxides in varying composition. The generic formula is frequently written as FeO(OH)·nH2O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely. Limonite is one of the three principal iron ores, the others being hematite and magnetite, and has been mined for the production of iron since at least 2500 BCE.
Limonite is extremely common and found worldwide. Excellent iridescent botryoidal masses have recently been found in China at Nandan, Guangxi Province, and at Qinglong, Guizhou Province. Excellent Limonite pseudomorphs after Pyrite come from Rio Marina, Elba Island, Italy; and Arenalejos, Carratraca, Spain.
Currently used for unidentified massive hydroxides and oxides of iron, with no visible crystals, and a yellow-brown streak. 'Limonite' is most commonly the mineral species goethite, but can also consist of varying proportions of lepidocrocite, hisingerite, pitticite, jarosite group species, maghemite, hematite, etc. Pronounciation of Limonite Hide.
LIMONITE Together with hematite, it has been mined as ore for the production of iron. Limonite is heavy and normally yellowish-brown but can be darker when mixed with iron ore.

Limonite is a common iron ore, which forms the coloring matter in different types of soils. It is usually formed from the chemical weathering of iron rich minerals, such as biotite, amphibole, pyroxene, and olivine, the hydration/oxidation of iron rich sulfide minerals, or
Limonite ore requires a stone pickaxe or higher to mine, anything lower than that will not have the ore drop. Natural generation [edit | edit source] Limonite ore generates in the overworld at layers 8-67. By default, the maximum amount of veins that will generate per chunk is 8.
Limonite is the catchall name widely applied to hydrous iron oxide minerals. Goethite [α-Fe 3+ O (OH)], which is hexagonal, is the most common of these minerals; indeed, in nature most FeO (OH) minerals ultimately become this α-phase. Goethite, much of which has the

Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. In 2011 the Financial Times has speculated that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
The Horton Limonite Mine was closed at the time of data entry with no known plans to re-open. Past operations took place around 1880. The ore mined is composed of limonite. The host rock in this area is shale from the Middle Ordovician epoch 470.00 to 458.40 million years ago. The New England Upland Section of the Appalachian Highlands ...
Limonite commonly forms as a precipitate around mine entrances, springs, bogs, and other shallow marine areas (1). Stratified deposits of limonite can be a sign that acid mining took place because they occur when the iron-rich water comes into contact with the oxygenated surface water and sink to the floor of the water body(1).
The Dakin Limonite Mine was closed at the time of data entry with no known plans to re-open. Past operations took place from 1734-about 1900. The ore mined is composed of goethite and limonite. The mineralization at this location is from the Holocene epoch 11,784 years ago to present. The Taconic Section of the Appalachian Highlands ...

Limonite is a common ore of iron and is always secondary in its origin, formed through the alteration or solution of previously existing iron minerals. Pyrite is often found altered to limonite, the crystal form being at times preserved, giving limonite pseudomorphs.

Goethite, a widespread iron oxide mineral [α-FeO(OH)] and the most common ingredient of iron rust. It was named in 1806 for J.W. von Goethe, a German poet and philosopher with a keen interest in minerals. The name was originally applied to lepidocrocite [γ-FeO(OH)], a less common mineral with the s

Used earlier by the iron and steel industry, limonite and other East Texas iron ores have more recently been mined for use in preparing portland cement, as a weighing agent in well-drilling fluids, and in animal-feed supplements. When iron production virtually ceased in 1910, less than 700,000 long tons of ore had been processed.
Goethite is found throughout the world, though collection-worthy specimens are less common. Branching stalactites and botryoidal masses, often associated with bright contrasting Vanadinite, come from the Four Man Mine, Taouz, Morocco.Recent finds of branching Goethite pseudomorphs after Marcasite are exceptional at the Farfara Oasis, in the White Desert of Egypt.

Limonite, or brown ore, is to be found at the bottom of some bogs and shallow lakes, in favorable situations, where the weathering rocks have yielded iron to the water draining into these basins. The limonite accumulates so fast in some places that a lake bottom may be cropped again after a number of years, as at Radnor Forges, Quebec.
As iron ores, limonite, goethite, and turgite have values similar to those of magnetite and hematite. Ore such as was mined originally at the Helen Mine, Michipicoten District Ontario, and more recently at Steep Rock Lake, Ontario, and on the vast new iron range in Labrador and New Quebec, ranks with the best hematite. Chromite: FeCr2O4
Small amounts of limonite discolor limestone, dolomite, clay, shale, sandstone, and gravel. Some sands are firmly cemented by brown or black limonite and look much like iron ore. Clays containing a high percentage of limonite are called ocher. In some states, limonite is mined as an iron ore.
Jun 12, 2014 · The nickel in the limonite zone is found within the iron oxides such as goethite and hematite. The saprolite and limonite zones tend to contain the higher grades of Ni and can range from 1.5-3% and 1.2-1.7% respectively.
