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

Iron Ore Mining and Processing

01/06/2015  In order to make steel, we first of all need to process the iron ore. The way the process goes is that the rock containing the ore is grounded carefully in order to separate it from the ore. Next, the coal will be properly cleaned from sediments in a coke furnace which yields an almost one hundred percent pure form of carbon.
