Environmental impact of iron ore mining - Wikipedia

Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined. Iron in ore iron is most commonly found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH)n(H2O)) or siderite (FeCO3). Roughly 98% of iron ore on the global market is used in iron and steel production. Common methods of extracting the iron ore consist of blasting, drilling, or general excavating, Most iro
