WebThe iron ore deposits began forming when the first organisms capable of photosynthesis began releasing oxygen into the waters. This oxygen immediately combined with the abundant dissolved iron to produce hematite or magnetite. These minerals deposited on the sea floor in great abundance, forming what are now known as the "banded iron formations."

WebNov 1, 2024 · Banded Iron Formation (BIF)-hosted iron deposits are the highest grade iron systems in the world and contribute the majority of iron ore supply to the global market. Aluminium is a major contaminant in all BIF-hosted iron ores and can occur as either discrete gangue minerals or as element substitution in the Fe-oxides (Paine et al., 2012). WebBanded iron formations (also known as banded ironstone formations or BIFs) are distinctive units of sedimentary rock that are almost always of Precambrian age.
