Extraction of Iron from its ores, Iron dressing, Reduction ...

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 - Mineral Properties, Photos and Occurence

Nov 22, 2018  Siderite is a member of calcite group minerals, which have a similar structure and form several solid-solution series. The miscibility of the calcite group members is limited though. Of the several possible members of the solid-solution series associated with siderite (FeCO 3), only the smithsonite (ZnCO 3), magnesite (MgCO 3) and rhodochrosite (MnCO 3) varieties are common.
