Steel production & environmental impact GreenSpec

1 Mineral Extraction. Iron ore. Iron doesn’t occur naturally. Being highly reactive, it combines easily with other minerals to form ores. Those with the highest iron content are found near the surface of the earth and are relatively easy to mine. The principal iron ores are hematite (Fe2O3) and magnetite (Fe3O4). Most iron ore is extracted through opencast mines. To be economically viable

Mines and environmental impact SGU

It is primarily from waste in the mining of sulphide ores that serious environmental problems can arise due to their content of iron sulphides such as pyrite and pyrrhotite. When mining waste containing iron sulphides is allowed to lie unsheltered and comes under the effects of weather and wind, it will crumble through an oxidation process. This weathering results in the release of an acidic

Iron ore Wikipedia

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO

The extraction of iron begins with concentration through calcination which is a process in a limited supply of oxygen applied to ores to bring thermal decomposition. An ore of a metal is an impure source. It consists of many impurities other than metal such as sand, clay, etc. These impurities are known as gangue which is commercially useless so we must separate it from ore. This process is
