Solved Today, Banded Iron Formations, A Type

Today, banded iron formations, a type of sedimentary rock found in many locations, provides evidence for the dramatic increase in oxygen released by cyanobacteria. Oxygen reacted with iron dissolved in the ocean. This created black iron oxide minerals (like hematite and magnetite).

Banded-iron formation (BIF) is consists of layers of iron oxides (typically either magnetite or hematite) separated by layers of chert (silica-rich sedimentary rock). Each layer is usually narrow (millimeters to few centimeters). The rock has a distinctively banded appearance because of differently colored lighter silica- and darker iron-rich layers.

What is iron ore? Quora

Sep 22, 2017Answer Wiki. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, or deep purple to rusty red. Despite the presence of other different minerals it's called iron ore only because the iron content is more in that.

Abstract To identify and establish beneficiation techniques for banded hematite quartzite (BHQ) iron ore, a comprehensive research on BHQ ore treatment was carried out. The BHQ ore was assayed as 38.9wt% Fe, 42.5wt% SiO 2, and 1.0wt% Al 2 O 3. In this ore, hematite and quartz are present as the major mineral phases where goethite, martite, and magnetite are present in small amounts.
