How Iron Ore Is Formed

Earths most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides hematite Fe2O3 and magnetite Fe3O4. We are here for your questions anytime 24/7, welcome your consultation.
