The Direct Reduction of Iron Ore

sponge iron so named because the removal of oxygen from iron ore without melting leaves a honeycomb microstructure that resembles a sponge The sponge iron was made by putting charcoal and iron ore in a shallow hearth in which intense heat was built up by directing a jet of air at the burn­ ing charcoal.
