2017-07-27  Siderite forms three solid-state solution series. It’s the iron (Fe) analogue in a series with manganese (Mn) dominant rhodochrosite. It also forms the Fe-end of a series with zinc (Zn) dominant smithsonite, as well as with magnesium (Mg) dominant magnesite. Siderite has been used as an iron ore and for steel production.

Siderite - Wikipedia

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

Siderite - Wikipedia

Siderite is also the name of a type of iron meteorite.Siderite is a mineral composed of iron(II) carbonate (FeCO3). 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.

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). Hence extraction of Fe from its ore (see Steel ...
