    The name banded iron formation comes from the characteristic colour banding of these huge deposits. The process continued for nearly a billion years and eventually let to the accumulation of oxygen in the atmosphere. Resources. Most of the world's important iron ore resources occur in banded iron formations which are almost exclusively of Precambrian age (i.e. greater than 541 million years

  • Origin Of Ore Deposits Processes of Ore Formation

    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.

    Ironformation ores include primary and enriched varieties. Primary magnetiterich ores are generally lower grade (<40 wt% Fe total) but have larger combined resources and reserves compared with enriched ores that have grades of 40 to 72 wt% Fe total.Enriched ores include early hypogene (magnetite crystalline hematite) and later supergene (goethitehematite) ore types.
