Association of Siderite with Iron Sulfides and Silicates in …

Abstract The mineral association of siderite with Cu–Fe sulfides, cronstedtite, and goethite were first recognized when studying the Mikheevskoe Cu(Mo,Au)–porphyry deposit. This association is confined to fault zones, where it fills a network of mineralized fractures developed on porphyry- and argillizite-type ores. Minerals of this association were also identified in some …

Siderite

Siderite —The mineral form of iron (II) carbonate, with the chemical formula Fe 2 CO 3 is called siderite. The mineral contains around 40%–48% iron and is a primary component of sedimentary rocks that assembles into the surrounding water bodies.

Siderite Fe2+ 3

Occurrence: A common component of bedded sedimentary iron ores and metamorphic iron formations; in hydrothermal metallic veins; rarely in granite and nepheline syenite pegmatites; …

OneMine | Mining East Texas Iron Ore

IRON ore reserves of Lone Star Steel Co. cover 56,000 acres in the north basin of the East Texas geosynclinal area near Daingerfield. Ore is almost wholly restricted to the Weches formation of middle Eocene Age. Its resistance to erosion has created the hilly topography of the East Texas area. The ore deposits, in the upper portion of the hills, are usually overlain with residual sand …

Siderite – WGNHS – UW–Madison

Siderite forms as a sedimentary precipitate, in hydrothermal veins, in metamorphic rocks formed from such protoliths, and, rarely, in pegmatites. In sedimentary environments it forms in extensive beds of banded iron formations and as more localized deposits of bog-iron ore. It readily weathers to iron oxides. ASHLAND COUNTY: Siderite is a common component of the Ironwood Banded …

Erzberg Mine in Austria: An iron ore reserve with a long tradition

The Erzberg Mine is the world's largest deposit of the iron mineral siderite (FeCO 3), which is mixed with ankerite (CaFe[CO 3] 2) and dolomite (CaMg[CO 3] 2). Due to this mixture of different mineral phases, the concentration of iron ranges from 22% to 40% and adopts an average value of 33%.

Siderite

Siderite is found in a wide variety of hydrothermal, metasomatic and sedimentary settings. It is a common mineral in sedimentary iron deposits or in metamorphic iron formations. Rarely as a primary magmatic mineral in carbonatites, syenites or pegmatites. Siderite is also rarely resent in some alpine type veins.
