Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities.
Pelletizing is the process of compressing or molding a material into the shape of a pellet.A wide range of different materials are pelletized including chemicals, iron ore, animal compound feed, and more.

This concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs. The extraction of iron from its ore is a long and subdued process, that helps in separating the …
Iron Extraction Process. In the blast furnace process, the first step on the way towards heavy plate, pig iron is produced from iron ore. The composition of the ore and additions is accurately adjusted to the final products of AG der Dillinger Hüttenwerke and Saarstahl AG.
Evolution of Blast Furnace Iron Making. ... as obtained from red iron ore. Developments in iron making process. Improvements in this first iron making process were made by lining the smelting hole with stones as well as mud and using bellows made of wood and leather (Fig 2). In China, the use of iron appeared about 600 BCE, spreading widely ...
Limestone is the reducing agent, without limestone the iron ore i.e Fe2O3 will never get reduced to Pig iron i.e Fe .. "calcination" should be lesser inside the blast furnace to reduce the coke rate that's why sinter is being used nowadays, as in sintering process limestone is calcinised outside the furnace which reduces the coke rate by 5–8%.
Charcoal blast-furnaces were used for many years to reduce the iron ore, but since 1910 the metallurgists have persevered with the electric furnace, according to Christiansen. After many trials with a 6,000-kv.-a furnace in 1925 and one of 9,000 kv-a in 1927.
The steelmaking process starts with the processing of iron ore. The rock containing iron ore is ground and the ore is extracted using magnetic rollers. Fine-grained iron ore is processed into coarse-grained clumps for use in the blast furnace.
process of separating the iron from the non-iron material. The magnetic iron ore is then laundered in two slurry surge tanks while the non-magnetics (silica/sand) go to the ... blast furnace process. The iron ore concentrate is now mixed and ready for the pelletizing process.
Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue". The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.
Blast furnaces are used to produce pig iron from iron ore for subsequent processing into steel, and they are also employed in processing lead, copper, and other metals. Rapid combustion is maintained by the current of air under pressure.
Iron processing Britannica. Iron processing Iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron and of its preparation for smelting. Read More; Blast furnace
The blast furnace ironmaking system using pre-reduced ore ("two- stage reduction system") is a two-stage ore reduction system that consists of a process for pre-reducing iron ore by using natural gas
Iron ore pelletizing. Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets. These are typically fed to a blast furnace or DRI plant as part of the process …
The ore is the transported to the various smelters located locally or on the other side of the world with large bulk carriers being used to ship the ore by sea. Iron Ore Smelting Process Using Modern Blast Furnaces.

The blast furnace process How does the transformation from iron ore to iron work and what role can plastic play? To remove oxygen (O) from iron ore and reduce iron ore (Fe2O3) to iron (Fe), reducing agents are required. A reducing agent is a substance which has a high affi nity interaction with the oxygen in iron ore. The
iron content ranges from 50% to 70%. This iron rich ore can be charged directly into a blast furnace without any further processing. Iron ore that contains a lower iron content must be processed or beneficiated to increase its iron content. Pellets are produced from this lower iron content ore. This ore is crushed and ground into a
Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide to elemental iron mixed with carbon.
Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements.
