Siderite is a common mineral and is found worldwide in many different environments. Only the most noteworthy will be mentioned here. Classic Siderite occurrences in Europe include Neudorf in the Harz Mountains, Germany; and Panasqueira, Portugal. Excellent gemmy greenish crystals come from Isere, (especially at Allevard), France.

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.

Siderite is also formed as iron rich waters replace Ca in limestone. Finally, it is a common vein mineral associated with various metallic ores, including the Precambrian banded iron formations. Importance in Soil Environments. Siderite may occur in soils in small quantities, particularly in fens receiving iron-rich waters. Graf, D.L. 1961.

Calcite Group. Magnesite-Siderite Series, Rhodochrosite-Siderite Series, Siderite-Smithsonite Series. Crystals typically found as brown to tan rhombohedrons in clusters, faces often curved or composites; more often found as medium to dark brown massive fine-grained material or as massive crystalline material with exposed curved cleavage surfaces.

The substitution of Mn for Fe in the structure of siderite, a common mineral in coal, is universal. The effects of Mn on the transformation of siderite during coaling and the de-NO performance of the transformed products in flue gas pipelines after injecting NH 3 were investigated, and a kinetic study was also performed. The results showed that the Mn-substituted siderite ((Mn, Fe)CO 3) was ...
