Banded iron formation

Numerous iron ore deposits are hosted within the Meso to Neo-Archean banded iron formations (BIFs) extending across the Singhbhum-Orissa Craton, eastern India Despite the widespread distribution of BIFs, which forms part of the iron ore group (IOG), heterogeneity in their grade and mineral composition is occasionally observed even within a single ore deposit Kiriburu-Meghahatuburu iron ore ....

Geological ore deposits

Iron ores of this type are commonly termed the banded iron formation or simply abbreviated as BIF All ore minerals in these deposits are oxides and hydroxid The most common iron ore minerals are hematite, lepidocrocite and goethite while the most common manganese ore minerals are braunite, manganite and hausmannite These deposits are ....

Banded iron formation to high

Laterite (sensu lato) is a soil formation in which primary textures are destroyed and is underlain by a pallid zone showing the preservation of chert and the depletion, not enrichment, of iron oxides and thus is totally incompatible with the formation of the high-grade ore deposits Various theories and models that purported to explain the ....

GEOLOGY AND GEOCHEMISTRY OF HIGH

1960s The early studies concluded that the high-grade iron-ore deposits were formed during the Mesozoic, due to the downward percolation of groundwater and subsequent leaching of silica, forming enriched residual iron-ore deposits (Stubbins et al, 1961; Gross, 1968) This super-gene model for the formation of high-grade iron-ore...

Banded Iron Formation

The spark to put together this volume on banded iron formation (BIF)-related high-grade iron ore was born in 2005 during a steamy night in Carajás where the iron research group from the Universidade Federal Minas Gerais, Vale geologists, Carlos Rosiére and Steffen Hagemann, were hotly debating the hypogene alteration genesis for the high-grade, jaspilite-hosted Serra Norte iron ore deposits...

Iron Ore Statistics and Information

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 (Fe3O4) and hematite (Fe2O3)...
