The iron is extracted from its oxide ore called hematite many things are produced in the extracting or iron from iron ore in a blast furnace the iron ore is reacted with carbon and oxygen in the furnace to produce carbon dioxide and iron metal carbon monoxide is also produced so that it can react with the iron ore to produce the iron at the end there is left the molten iron and the slag the top of the furnace
