Sponge Iron an overview | ScienceDirect Topics

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 The reduction takes place using gaseous reductants (CO + H

MAKING OF IRON NUGGET FROM CONCENTRATED IRON SAND
