Sedimentary rock Iron-rich sedimentary rocks Britannica

Sedimentary rock Sedimentary rock Iron-rich sedimentary rocks: Almost all sedimentary rocks are iron-bearing in the sense that mudrocks, sandstones, and carbonates typically have an iron content of several percent. Nevertheless, sedimentary rocks in which the proportion of iron exceeds 15 percent are separately categorized as iron-rich. Two major types of iron-rich sedimentary rocks are

Ironstone Wikipedia

Ironstone is a sedimentary rock, either deposited directly as a ferruginous sediment or created by chemical replacement, that contains a substantial proportion of an iron ore compound from which iron (Fe) can be smelted commercially. Not to be confused with native or telluric iron, which is very rare and found in metallic form, the term ironstone is customarily restricted to hard, coarsely banded, non-banded, and non-cherty sedimentary rocks of post-Precambrian age. The Precambriandeposits, which have a different orig

Michigan iron ore is found as isolated masses in a Huronian rock called iron formation. Iron formation is a banded sedimentary rock commonly composed of layers of silica (the mineral of sand and glass), alternating with layers of iron minerals. Such rock is found only in very old rocks, the Precambrian (fig. 3). Conditions for banded

Iron processing Iron processing Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is
