The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved, the processes inside the blast furnace remain the same. The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal is a key part of the coke-making process.
Both processes can be used to generate almost any type of desired pellet chemistry, from direct reduction pellets DR pellets to blast furnace pellets. By adjusting the amount of fluxing agent or limestone added, pellets can be made that are anywhere from acid or

The pure metals can be extracted by reduction. Iron is obtained from ironIII oxide by reacting with carbon at high temperatures. The removal of oxygen from the Fe 2 O 3 means that it is being reduced to Fe. Note that an oxidation process is simultaneously occurring. The carbon reactant is being oxidized to CO 2 . This is an important concept.
Abstract. The possibility of using methane gas for the direct reduction of ferrous oxide is discussed. On the basis of theoretical considerations and experimental results, the conclusion is drawn that, by introducing the methane directly in the reaction space, both the reduction of oxides into metallic iron and the continual regeneration of the reducing agents can be achieved.
