About Sponge Iron. Direct-reduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture, the majority of which is hydrogen (H2) and carbon monoxide (CO) which act as reducing agents.

Sponge Iron | SpringerLink

Densification of Sponge Iron: By hot pressing of sponge iron (lumps and pellets) at 700–800 ℃, hot briquetted iron (HBI) is formed. This results in substantial improved physical properties, namely higher densities (apparent and bulk, as shown in Table 7.7 ) and decrease in its surface area and porosity.
