One of the largest and most significant iron ore deposits in the world is the Pilbara region in Western Australia. The iron ore found there is mainly of the banded iron formation (BIF) type. BIFs are sedimentary rocks containing alternating layers of iron-rich minerals and chert. The Pilbara region is known for its high-quality hematite and, to a lesser extent, magnetite iron ore deposits. These deposits play a crucial role in global iron ore production.
