how is iron ore obtained
Iron Ore Processing, General
There is a long and rich history of iron ore mining and processing. Prior to the industrial revolution, most iron was obtained from widely available goethite or bog ore. Prehistoric societies used laterite as a source of iron ore. Historically, much of the iron ore utilized by industrialized societies has been mined from predominantly

Extraction of Iron from Hematite
Carbon monoxide reduces the iron(III) oxide in the iron ore to form iron This will melt and collect at the bottom of the furnace, where it is tapped off; iron(III) oxide + carbon monoxide → iron + carbon dioxide. Limestone (calcium carbonate) is added to the furnace to remove impurities in the ore
