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.

· Sponge iron is a metallic product made through the direct reduction of iron ore in the solid state. It is also known as naturally reduced iron (DRI). The process of making sponge iron aims to expel oxygen from the iron ore and increase its quality. Compared to conventional blast furnaces, this method reduces steel production costs
