My friend and I would like to know how to get iron from iron ore, but we do not know how to separate the iron and silicon dioxide and other impurities, and I am horrible with research, so I couldn‘t find anything online.
STRAIGHT FROM PEDIA Blast furnace Main article: Blast furnace Ninety percent of all mining of metallic ores is for the extraction of iron[citation needed]. Industrially, iron production involves iron ores, principally hematite (nominally Fe2O3) and magnetite (Fe3O4) in a carbothermic reaction (reduction with carbon) in a blast furnace at temperatures of about 2000 °C. In a blast furnace, iron ore, carbon in the form of coke, and a flux such as limestone (which is used to remove silicon dioxide impurities in the ore which would otherwise clog the furnace with solid material) are fed into the top of the furnace, while a massive blast of heated air, about 4 tons, per ton of iron[38], is forced into the furnace at the bottom. Iron output in 2005 In the furnace, the coke reacts with oxygen in the air blast to produce carbon monoxide: 2 C + O2 → 2 CO The carbon monoxide reduces the iron ore (in the chemical equation below, hematite) to molten iron, becoming carbon dioxide in the process: Fe2O3 + 3 CO → 2 Fe + 3 CO2
