Carbon monoxide reduces the iron(III) oxide in the iron ore to form iron This will melt and collect at the bottom of the furnace, where it is tapped off. iron(III) oxide + carbon monoxide → iron + carbon dioxide. Limestone (calcium carbonate) is added
More2014年9月8日 Pelletization is the process of making spheres of uniform quality iron ore with high carbon content. Iron ore is pelletized so that it can efficiently flow through a blast furnace for smelting. The process involves mixing iron ore fines with additives like limestone, dolomite, and bentonite. This mixture is then formed into balls on a balling ...
