Iron Ore Processing: From Extraction to Manufacturing

In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top. The intense heat generated by the combustion of coke reduces the iron oxides in the ore to metallic iron. The limestone or dolomite reacts with impurities, forming a slag that floats on top of the molten iron.
