Banded iron formation WikipediaHow Is Iron Extracted From the Earth Reference

A typical banded iron formation consists of repeated thin layers a few millimeters to a few centimeters in thickness of silver to black iron oxides either magnetite Fe 3 O 4 or hematite Fe 2 O 3 alternating with bands of iron poor shales and cherts often red in color of similar thickness and containing microbands sub millimeter of iron oxidIron ores in the form of hematite ferrous oxide and magnetite are removed from the earth through mining The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore however because iron does not occur naturally it is necessary to use a blast

A nearly 3 billion year old banded iron formation from Canada shows that the atmosphere and ocean once had no oxygen Photosynthetic organisms were making oxygen but it reacted with the iron dissolved in seawater to form iron oxide minerals on the ocean floor creating banded iron formationsIn Early Proterozoic 25 to 16 billion year ago iron ore deposits layers of hematite and other iron oxides alternate with bands of chert microcrystalline quartz to form distinctively layered deposits known as Banded Iron Formation
