Iron ore :: ArcelorMittal Liberia

Our Liberian iron ore is a siliceous goethite/ hematite/ magnetite iron ore, containing approximately 60% Fe, 10% SiO2, 2% Al2O3 and 0.1% P . It is derived from a banded iron formation (BIF), deposited in layers of enriched iron and silica by sedimentation at the bottom of the ocean over many centuries. These ocean floors have been folded and moved by tectonic forces to become what we know
