Iron is extracted from the ore containing the maximum amount of iron This is found near the surface of the Earth Iron ore is converted to iron by various processes The most common process is the use of a blast furnace to extract pig iron Pig iron comprises of about 9294 iron and about 35 of carbon along with other impurities
It is estimated that the earth’s core contains huge quantities of iron It is not found in the Free State but occurs in the combined state with other elements Its chief ores are magnetite
Iron is extracted from the earth as a metallic ore Then it is processed in a steel mill Since that moment it is called steel

iron III oxide carbon → iron carbon monoxide Fe2O3s 3C s → 2Fe l 3CO g This method of extraction works because carbon is more reactive than iron so it can displace iron
The melted iron comes out from the bottom of the furnace which on cooling becomes solid The iron so obtained is called ‘pig iron’ or ‘cast iron’ It contains 5 of carbon After reducing the percentage of carbon from 2 to 02 it is converted into steel Iron and steel are very useful for us
Nov 21 2014 · Iron is an element that is not found in Free State but rather in the form of its ores or rocks The most commonly found ores of iron are Hematite and Magnetite These are oxides of iron that are extracted from beneath the surface of the earth’s crust and sent to blast furnaces to make pig iron This iron is then used to manufacture steel
Apr 25 2017 · Iron ore being extracted at the massive Mikhailovsky Mine in Russia Iron has a chemical formula Fe and it is one of the most common elements in the world and forms 5 of the crust of the Earth It ranks the fourth among the common elements after Oxygen Silicon and Aluminum Iron forms a critical part of modern civilization and its use
Jul 06 2016 · Less reactive metals like iron can be extracted with reduction where oxygen is removed from the ore through a reaction with carbon or carbon dioxide Many rare earth elements on the other hand mostly undergo complex chemical processing to be separated from the ore minerals and this is in part what makes them so expensive to mine according
