Banded Iron Formation Mining Fundamentals

Apr 29 2014. Banded iron formations (BIFs) are sedimentary rocks, characterized by the presence of alternating layers of iron-rich minerals - known as magnetite - and amorphous silica-rich rocks - known as cherts. Each layer is relatively thin with varying levels of thickness, measuring from a millimeter up to several centimeters.
