  • 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

  • Effects of iron-ore mining and processing on metal

    On one hand, iron-ore mining and processing constitute potential sources of metals to the lagoon, on the other hand they also contribute to reducing metal bioavailability. The low metal bioavailability in the lagoon is mainly because of the high content of ligands, partly released by the mining, such as carbonates, and partly naturally found in the lagoon, such as DOC and chloride.
