Direct Reduction Process - an overview ScienceDirect

DRI is also known as sponge iron, it is a solid-state direct reduction process (Fig. 2.6). Coal, dolomite and iron ore or pellets are fed into one end of a rotary kiln, while sponge iron and char are withdrawn from the other end. Primary and secondary airs are supplied to the kiln to initiate combustion and reaction processes (Choudhury, 2014).
