Feb 22, 2017 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.
May 10, 2021 Iron ore producing companies supply a vital component of modern industry, with iron ore used across the world primarily as an ingredient in steel manufacturing. The metallic ores, which can vary in colour from dark grey and bright yellow, to purples and reds, comprise around 5 of the Earth’s crust and are commonly found in four main types of.
The world's resources are dominated by low-grade ore, though current world production of iron ore is largely by supply from deposits of high-grade ore composed of either rocks of massive hematite or pisolitic goethite.
