magnetite ores can be used in blast furnace. magnetite ore use in blast furnace - natureslimsecrets. The magnetite Fe 3 O 4ore cannot be used in the blast furnaces and sintering plants directly ore is not directly because of the high sulfur content Sulfur and alkalines are reduced by using ore preparation process, pellets are formed by crushing, grinding, separating and induration process
How Is Iron Extracted From the Earth but the complete reduction reaction requires the addition of coke and limestone to the roasted ore. After the completion of different processes in the blast furnace, molten iron flows from the bottom of the blast furnace. This molten iron may be utilized as cast iron.get price

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 which controls the input.
How a Blast Furnace Works - American Iron and Steel Institute. The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone
The method. Three substances are needed to enable to extraction of iron from its ore. The combined mixture is called the charge. Iron ore, haematite - often contains sand with iron oxide, Fe 2 O 3.. Limestone calcium carbonate.. Coke - mainly carbon.. The charge is placed a giant chimney called a blast furnace. The blast furnace is around 30 metres high and lined with fireproof bricks.
Tick two reasons why limestone is added. Reduces iron ore to iron Produces carbon dioxide Lowers the melting point of iron Removes siliconIV oxide from the furnace 2 b 48 tonnes of an iron ore is used in a blast furnace to produce iron. 11.2 tonnes of iron is produced.

A blast furnace is charged with iron ore, charcoal or coke coke is charcoal made from coal and limestone CaCO 3 . Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag. get price
in a huge container called a blast furnace. Iron ores such as haematite contain ironIII oxide, Fe 2 O 3.The oxygen must be removed from the ironIII oxide in order to leave the iron behind.
In a blast furnace, fuel coke, ores, and flux limestone are continuously supplied through the top of the furnace, while a hot blast of air sometimes with oxygen enrichment is blown into the ...
Limestone Its Processing and Application in Iron and. Jul 07, 2017 Application of limestone and lime in iron and steel plant. During the production of iron by blast furnace BF route, limestone is added either in the process of sintering or as a direct feed in the blast furnace.
Quicklime CaO is formed during iron making from added limestone CaCO 3. The heat in the blast-furnace decomposes the limestone to quicklime which then reacts with the impurities and produces the slag. Blast-furnace slag is a useful by-product used widely in the construction industry. Removing sulfur impurities. Iron from the blast-furnace ...
Blast Furnace Slag - Material Description ORIGIN In the production of iron, iron ore, iron scrap, and fluxes limestone andor dolomite are charged into a blast furnace along with coke for fuel. The coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product.
why limestone is charged in blast furnace Grinding . limestone is charged in blast furnace Primary Metal Production. These are vertical furnaces with the charge added at the top and removed at the . Limestone is also a better flux to use if slag from the. Read more
The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.
Limestone Air Each of the raw materials is necessary for the production - click to see its purpose. The blast furnace. The iron ore, coke and limestone charge is fed into the blast furnace from the top. Once inside the hot furnace the coke reacts with the blast of air containing oxygen making carbon monoxide gas.
It is this calcium oxide that is added to the process. The primary impurity in any ore is silica or silicon dioxide, SiO2, which remains a solid even at blast furnace temperatures. However, the silicon dioxide must be removed both for purity of the iron and to prevent the furnace from clogging up.
Iron is extracted from its ore, haematite, in a blast furnace. The ore is fed into the top of the furnace along with coke and limestone. ... The limestone decomposes in the hot furnace, forming calcium oxide. This reacts with the sandy impurities silicon dioxide to form a slag.
Limestone which is a sedimentary rock is a valuable resource from the Earths crust. It has many uses. Limestone is also used to remove impurities from the blast furnace when making iron ...
