Lateritic weathering of metamorphosed Proterozoic banded iron-formation (BIF), locally named itabirite in Brazil, produced large deposits of iron ore. At the Capanema iron-ore mine in the Quadrilatero Ferrifero in Minas Gerais state (southeast Brazil), the BIF is a bedded metasedimentary rock composed essentially of layers of hematite/kenomagnetite alternating with layers of quartz.

A significant proportion of Brazil’s iron ore does not require much processing, especially in the Para state, home to Vale’s Northern System. However, most of the country’s iron ore is produced in the Minas Gerais, a state dominated by a type of ore called Itabirite that has an Fe content between 30–58%.

Itabirite - Wikipedia

Itabirite, also known as banded-quartz hematite and hematite schist, is a laminated, metamorphosed oxide-facies iron formation in which the original chert or jasper bands have been recrystallized into megascopically distinguishable grains of quartz and the iron is present as thin layers of hematite, magnetite, or martite (pseudomorphs of hematite after magnetite).
