Direct reduction is a gas-based iron-making technology, using natural gas instead of coke. The natural gas reacts with CO 2 to CO and H 2. The CO then acts as reducing agent. Smelt reduction technology is a coal-based iron making process. Smelting reduction technology, as the name clearly suggests, involves both solid-state reduction and melting.

Gas from coal is expected to find some application in direct reduction of iron ore and may be used in other applica- tions where a reducing gas is needed, e.g., to regenerate sorbent materials used in flue gas cleaning systems for col- lection of S02.
The production of iron or steel is a process unless the desired final product is cast iron. The first stage is to produce pig iron in a blast furnace. The second is to make wrought iron or steel from pig iron by a further process.
