Processes that produce iron by reduction of iron ore in solid state are generally classified as direct reduction (DR) processes and the products also referred to as direct reduced iron (DRI) or sponge iron. Different processes of coal-based and gas-based are discussed in detail. Forms of sponge iron, characteristics of sponge iron and re-oxidation of sponge iron are described. Uses of sponge iron are also discussed.
