Mineral deposit - Iron deposits | Britannica

Mineral deposit - Mineral deposit - Iron deposits: By far the most important metal from an economic and technical point of view is iron. Sedimentary iron deposits, from which almost all iron is obtained, can therefore be viewed as one of the world's great mineral treasures. There are two major types of deposit. The first, and by far the most important, is banded iron formations (BIFs), so ...

Siderite - Wikipedia

Siderite is a mineral composed of iron(II) carbonate (FeCO 3).It takes its name from the Greek word σίδηρος sideros, "iron". It is a valuable iron mineral, since it is 48% iron and contains no sulfur or phosphorus. Zinc, magnesium and manganese commonly substitute for the iron resulting in the siderite-smithsonite, siderite-magnesite and siderite-rhodochrosite solid solution series.

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 ...

Siderite - an overview | ScienceDirect Topics

Iron ore consists primarily of hematite (Fe 2 O 3) and magnetite (Fe 3 O 4) in proportions which vary appreciably among ore bodies, as well as variously hydrated hematites, siderite (FeCO 3), and pyrite (FeS 2). Among impurities present, again in widely varying proportions, the most important are lime (CaO), silica (SiO 2) and alumina (Al 2 O 3).

Different Types of Iron Ore - Mineral Processing & Metallurgy

Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.
