DRI also known as sponge iron is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron below the melting point of iron and typically in the range of 8001200 C Iron oxide is charged into shaft furnace rotary kiln or fluidized beds in the form of pellet iron ore lumps or fines The reduction takes place using gaseous reductants CO H Oct 10 2017 Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities The iron ore is dressed or crushed into 051 in chunks which increases surface area for reactions Magnetic separation is used to remove some of the undesirable minerals or gangue in the crushed ore
