• Different Types of Iron Ore - Mineral Processing & Metallurgy

    On the basis of their time of formation relative to host rock, the ore deposits are divided into two groups: Syngenetic Ore Deposit: The ore deposits that are formed at the same time as the enclosing rock are called “Syngenetic ore deposits”. Sedimentary ore deposits are the examples of syngenetic deposits.

    An ore is an economically exploitable mineral or an association of minerals (rock). Iron ore, for example, which is our main product, occurs in its oxide, carbonate, sulphate and silicate forms. The largest sources of iron ore on the planet are known as banded iron formations (BIFs), known …

  • Iron Ore Statistics and Information - usgs.gov

    The iron ore formation started over 1.8 billion years ago when abundant iron was dissolved in the ocean water which then needed oxygen to make hematite and magnetite. The oxygen was provided when the first organism capable of photosynthesis began releasing oxygen into the waters.

  • Ore genesis - Wikipedia

    Iron Ore Formation. Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without ...

    Bog iron is a form of impure iron deposit that develops in bogs or swamps by the chemical or biochemical oxidation of iron carried in solution. In general, bog ores consist primarily of iron oxyhydroxides, commonly goethite (FeO(OH)).. Iron-bearing groundwater typically emerges as a spring.The iron is oxidized to ferric hydroxide upon encountering the oxidizing environment of the …

    Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.
