Step 1: The Iron ore is crushed and broken into smaller pieces, concentrated with gravity separation process (washed with water). Step 2: The raw materials are added into the top of the furnace : Iron ore (Haematite, Fe2O3), Coke (Carbon, C), Limestone (CaCO3) Step 3: It is heated by blowing hot air at the base of the blast furnace.
EXTRACTION OF IRON IN A BLAST FURNACE Iron is also below carbon in the reactivity series, so therefore carbon can be used to reduce it (note: reduction can also mean to remove the oxygen from a compound). This is done in a blast furnace. The most common ore of iron is called haematite (iron(iii) oxide). Its formula is Fe 2 O 3.
Oct 23, 2018· Extraction of Iron from its ores. Extraction of iron or its metallurgy is the process of obtaining this metal in a form where it can be put to practical use, and this process of extraction consists of three stages: Ore dressing, Reduction of ores and Iron production. Extraction of Iron from its ores.
Blast furnace, a vertical shaft furnace that produces liquid metals by the reaction of a flow of air introduced under pressure into the bottom of the furnace with a mixture of metallic ore, coke, and flux fed into the top. 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.

Iron Extraction Manufacturing Process - Blast Furnace Method. Iron is extracted from different ores exist in the world. Hematite (Fe 2 O 3) is reduced to iron metal in the blast furnace under several steps. Limestone and coke are used as other raw materials to generate heat and reducing agents.
The sintering process begins with the preparation of a sinter mixture consisting of iron ore fines, fluxes, solid fuel (called bonding agents in Japan) such as coke breeze, and return fines from the sinter plant and blast furnace as well as recycled ferruginous materials from downstream iron …
The process of the extraction of iron is carried out by the following steps. Extraction of metal from concentrated ore. The basic oxygen. The iron in the chalcopyrite ends up converted into an iron ii silicate slag which is removed. Concentration of ore calcination or roasting of ore reduction of ore.
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 …
Jul 21, 2014· Iron ores are reduced by coke (carbon) in a blast furnace. The process is summarised in the diagram below. Hottest part of the furnace At the bottom of the furnace, adjacent to the hot air blast entry points, the temperature reaches around 1800ºC, and represents the hottest part of the furnace. Ascending vertically, the furnace temperature…
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.
