Environmental impact of iron ore mining Wikipedia

Introduction Iron ore. 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 (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH)n(H 2 O)) or siderite (FeCO 3).Roughly 98% of iron ore on the global market is

Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. The heat of the furnace causes the decomposition of the limestone for producing calcium oxide. CaCO 3-----> CaO + CO 2.

Iron ore Wikipedia

Iron is the world's most commonly used metal—steel, of which iron ore is the key ingredient, representing almost 95% of all metal used per year.
