Although spathic (carbonate) iron ores, such as siderite, have been economically important for steel production, they are far from ideal as an ore. Their hydrothermal mineralisation tends to form them as small ore lenses, often following steeply dipping bedding planes. This makes them not amenable to opencast working, and increases the cost of working them by mining with horizontal stopes. As the individual ore bodies are small, it may also be necessary t
The accepted classification scheme for iron-rich sedimentary rocks is to divide them into two sections: ironstones and iron formations Ironstones consist of 15% iron or more in composition. This is necessary for the rock to even be considered an iron-rich sedimentary rock. Generally, they are from the Phanerozoic which means that they range in age from the present to 540 million years ago. They can contain iron minerals from the fol
Siderite is named for the Greek word for iron, sideros.The word siderite is used in a number of rarer minerals and except in the fact that they all contain iron, they are otherwise unrelated to siderite.

concretions contain iron-oxide pseudomorphs after siderite (Loope et al., 2011). These relation-ships indicate not only that the concretions of the Navajo Sandstone had siderite precursors, but also that these formed during late diagenesis. Siderite is easily overlooked both in the field and in the laboratory (Berner, 1971). Because it is
Jan 12, 2020· Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.
Oct 31, 2010· Therefore, the average valency of iron in Fe3O4 is 8/3, a rare example of fractional valency made possible only by the fact that iron in this compound actually exists in two integral valence
Iron processing Iron processing Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine.
It is a valuable iron mineral, since it is 48% iron and contains no sulfur or phosphorus. Both magnesium and manganese commonly substitute for the iron. Siderite has Mohs hardness of 3.75-4.25, a specific gravity of 3.96, a white streak and a vitreous lustre or pearly luster. Siderite is a mineral composed of iron(II) carbonate (FeCO3).
