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 ...

A particular feature in the depth variations of χ is the lower values obtained in the topsoil part, while a maximum χ is linked to the B horizons (van Dam et al., 2008). According to the authors, the range of iron oxide forms detected—goethite, hematite, magnetite/maghemite—is related to the degree of weathering and exposure to soil erosion.

How can I find the depth to the water table in a specific ...

The depth to the water table can change (rise or fall) depending on the time of year. During the late winter and spring when accumulated snow starts to melt and spring rainfall is plentiful, water on the surface infiltrates into the ground and the water table rises. When water-loving plants start to grow again in the spring and precipitation gives way to hot, dry summers, the

Study on kinetics of thermal decomposition of low LOI ...

Hydrated minerals in these hematite iron ores are kaolinite, gibbsite and goethite, which contribute to the loss on ignition (LOI) during thermal decomposition. Experiments in fixed bed have been carried out at variable bed depth (16, 32, 48 and 64 mm), temperature (400–1200 °C) and residence time (30, 45, 60 and 75 min) for iron ore samples.

Pegmatite - Wikipedia

A pegmatite is an igneous rock, formed by slow crystallization at high temperature and pressure at depth, and exhibiting large interlocking crystals usually greater in size than 25 mm (0.98 in). Most pegmatites are intrusive rocks found in sheets of rock (dikes and veins) near large masses of igneous rocks called batholiths.. The word pegmatite derives from Homeric Greek, πήγνυμι ...
