The corresponding premium for blast furnace (BF)-grade magnetite concentrate is 17 per cent, which demonstrates the dependency on grade. The capital expenses for a 14 Mt/a concentrate plant is estimated at US$3.1 B for BF-grade magnetite and US$3.35 B for DR-grade, with operating expenses at US$45 and US$50 respectively. The corresponding free on board price for a break-even net present
Iron ore is used to make iron and steel eg haematite and magnetite. Iron is produced (extracted) in a blast furnace by reducing iron oxides with carbon and it is the carbon that removes the oxygen from the iron oxides – the carbon is known as the reducing agent. Coke

The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal state. A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottom. All the three ingredients are crushed into small round pieces and mixed and put on a hopper
Magnetite is a valuable source of iron ore and is mainly used in making steel. In a blast furnace, iron ore, carbon in the form of coke, and a flux such as limestone (which is used to remove impurities in the ore which would otherwise clog the furnace with solid material) are fed into the top of the furnace, while a blast of heated air is forced into the furnace at the bottom. In the
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. A zinc-lead blast furnace and lead-splash condenser.

The principal iron ores are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). Almost all iron ore is used in blast furnaces to make pig iron, which is the main material for steelmaking. Small amounts of iron ore are used in other applications such as coal wash plants and cement manufacturing. Iron is the most used metal accounting for about 95% of total metal tonnages produced worldwide.
The blast furnace (BF) is the most widely employed reactor for iron production since the iron and steel begin to be used on a large scale. In the ironmaking process, the gas utilization e ciency is an important index since it can reﬂect the overall performance of the BF, which is related to the utilization of energy. In the BF, the reducing gas (mainly carbon monoxide, i.e., CO) is utilized
Most of the iron and steel industry's emissions occur during production of iron in the blast furnace, where coal and coke are used as fuel and as a reducing agent. Magnetite has low external fuel requirements during induration as it is exothermic, releasing latent energy in the form of heat as it oxidises. This quality reduces the production costs, increases productivity, improves competitiveness and leaves a smaller
Magnetite is used for the preparation of heavy media in coal washing plants. Iron fines are also used in pipe coating. Metallurgical uses: Most important use of iron is in the blast furnace for the production of pig iron. It is used in the furnace in the form of sinters and pellets as also lumpy ore. It is also consumed in the open health furnaces.
blast-furnace technology for the melting of the titanium-vanadium-magnetite concentrate suitably prepared in the form of sinter or pellets. vanadium in the titanium-vana-dium-magnetite concentrate does not prevent it from being directly used for the blast-furnace charge. Titanium, if intro-duced to the blast furnace in excessive amounts, may cause
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 useful components from the waste materials such as slag. What happens in the Blast Furnace? The purpose of a Blast Furnace is to reduce the concentrated
blast furnace process. The iron ore concentrate is now mixed and ready for the pelletizing process. Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about the size of a marble (between 1/4" and 1/2"). Pellets are screened to meet the size specification
Blast furnaces existed in China from about 1st century AD and in the West from the High Middle Ages.They spread from the region around Namur in Wallonia (Belgium) in the late 15th century, being introduced to England in 1491.The fuel used in these was invariably charcoal.The successful substitution of coke for charcoal is widely attributed to Abraham Darby in 1709.
If the iron ores, which have not yet been reduced, move further down in the blast furnace, then the carbon can also directly reduce the iron oxides contained in the ore due to the high temperatures. The carbon ((C)) is oxidized to carbon monoxide ((CO)) by the absorption of oxygen ((O)). Due to the direct reduction of iron oxides by carbon, one also speaks of a
