Phosphosiderite is a very dense stone that can be scratched by a knife blade or steel file. It has a Mohs hardness of 5-6 and a specific gravity of 4.04 to 4.14 with its streak being white. This stone was first discovered in 1823 in the Strontian mines in Strontian, Scotland, and named after its presence in that area.

Banded iron formations (BIFs) host the world's largest iron ore deposits, and they formed predominantly through the deposition of ferric iron [Fe(III)] from ferruginous oceans during the Archean Eon (1, 2).Most models for BIF deposition invoke photosynthesis in the oxidation of ferrous iron from seawater to induce its subsequent precipitation and …

In Brazil, some ore that contains practically no other minerals can grade as high as 68% Fe, but the crude ore mined in Canada grades between 30 and 44% Fe. Therefore, these mines …
The formation of ferrous carbonate mineral is a significant geochemical reaction linked to iron and carbon cycling in the sedimentary environment. However, knowledge of the controlling factors and conditions for the mineral formation is limited. Two types of ferrous carbonate mineral, siderite (FeCO3) and chukanovite …
Siderite is a mineral that is characterized by a pearly or vitreous luster and white streak with a specific gravity equivalent to 3.96, and 3.75 to 4.25 Mohs hardness. Siderite is the major byproduct of corrosion that signifies corrosion caused by carbon dioxide. Most materials made from steel are prone to CO 2 corrosion when CO 2 partial ...
Limonite and siderite ores were recovered from open-pit mines in Cass, Cherokee, Henderson, and Morris counties. In 1985 Texas exported 1,116 short tons of iron ore to foreign countries and 22,237 short tons domestically, in addition to receiving significant imports. The last mining of iron ore for metal manufacture ceased in the mid …

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.

USES. Siderite is an ore of iron in some iron deposits. NOTEWORTHY LOCALITIES. Siderite is a common mineral and is found worldwide in many different environment s. Only the most noteworthy will be mentioned here. Classic Siderite occurrences in Europe include Neudorf in the Harz Mountains, Germany; and Panasqueira, Portugal.
Siderite iron ore is a hard and dense carbonate of iron, containing no sulfur or phosphorus and is mixed with carbonates such as magnesium, manganese, and calcium. Siderite is roughly the equivalent of calcite but with iron replacing the calcium. Formula of siderite: FeCO 3. Iron content: Up to 48.2%.
