  • Siderite Wikipedia
    OverviewSpathic iron oreGallery

    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

    The accepted classification scheme for iron-rich sedimentary rocks is to divide them into two sections: ironstones and iron formations Ironstones consist of 15% iron or more in composition. This is necessary for the rock to even be considered an iron-rich sedimentary rock.

Sulphur in the ore goes partly into the iron and steel and makes them brittle. While it is possible by roasting the ore and by other means to remove the sulphur, the presence of any considerable amount is objectionable. Phosphorus in steel makes it brittle. For steel-making the limit for phosphorus is one hundredth of one per cent for ten per cent of iron in the ore; this is the so-called Bessemer...
