Since DRI is produced by removing oxygen from iron ore, its structure is just like a sponge with a network of connecting pores. These pores result in a large internal surface area which is about 10,000 times greater than the internal surface area of solid iron. Due to this, DRI is also known as Sponge Iron.

Sponge Iron
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 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines.
