Iron ore: how our greatest asset is formed

Iron ore, for example, which is our main product, occurs in its oxide, carbonate, sulphate and silicate forms. The largest sources of iron ore on the planet are known as banded iron formations (BIFs), known in Brazil as itabirites and jaspelites. The rock in these formations undergoes intense physical and chemical processes that result in the
