In contrast to the blast furnace process, the direct-reduced iron process operates at temperatures of up to 1000 °C. The iron ores are therefore not melted! This also applies to the gangue contained in the ore, which is why the iron ores used must be relatively low in gangue from the outset. The reduction gases only dissolve oxygen from the ...

roads for removing iron ore and charcoal to the furnace. Iron ore is iron oxide (Fe304 or Fe203) or iron carbonate (FeCO3). The ore is converted to metallic "pig iron", not by melting but through a "reduc-tion" process where oxygen is chemi-cally removed. This is accomplished by burning charcoal at 3,000 oF with a

Iron ore is a rock or mineral from which metallic iron can be extracted economically. It constitutes 5% of the earth's crust. Viable forms of ore contain between 25% and 60% iron. Ore greater than 60% iron is known as natural ore or direct shipping ore, meaning it can be fed directly into iron-making blast furnaces.
