Jun 30, 20160183;32;Resource figures are current as at 30 December 2015. Commentary is current as of December 2016. Iron (Fe) is a metallic element that constitutes about 5.6% by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted.
Iron ore is mixed with coking coal and limestone and heated in a blast furnace. The coke burns in a forced stream of preheated air , and reduces the iron oxide to iron, releas ing carbon monoxide. The limestone reacts with the impurities in the iron ore (earth, rock, etc.) as
