Sep 01, 2016· This study conducts a life cycle assessment for iron and steel production in Turkey using SimaPro software and IMPACT 2002+ impact assessment method with the purpose of comparing the impacts of processes (coke making, sintering, iron making, steel making) and final products (billet, slab, hot rolled wire rod, hot rolled coil), concurrently.
Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore requires ...

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.
