    Blast furnace process

    If the iron ores, which have not yet been reduced, move further down in the blast furnace, then the carbon can also directly reduce the iron oxides contained in the ore due to the high temperatures. The carbon (\(C\)) is oxidized to carbon monoxide (\(CO\)) by the absorption of oxygen (\(O\)).Iron ore must go through a lengthy pre-processing stage before it can be pelletized a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore.Read more
