The integrated iron and steelmaking route involves blast furnace (BF) ironmaking followed by basic oxygen furnace (BOF) steelmaking. The BF uses sinter, pellets, and lump ore as iron-bearing raw materials, and coke and pulverized coal as fuel and reducing agents to produce hot metal with consistent quality for the BOF process.
9.3.2 Extraction of Iron from Hematite
Extraction of Iron from Hematite. Iron is extracted in a large container called a blast furnace from its ore, hematite. Modern blast furnaces produce approximately 10,000 tonnes of iron per day. The process is demonstrated and explained below: Diagram showing the carbon extraction of iron. The raw materials: iron ore (hematite), coke (an impure ...

A blast furnace can be used to extract iron from its ore. Components other than just the ore are added to the furnace to extract the iron. One of these key components is limestone, which is primarily composed of calcium carbonate, CaCO3. The heat from the blast …
Making iron & steel
Before iron ore can be used, oxygen must be removed from it. Known as 'reducing', this can be done either in the blast furnace, where hot air is injected into a continuous feed of coke, sinter and lime, or by the direct reduced iron (DRI) process. The result from both is liquid iron, which is then transported to the basic oxygen furnace. The blast furnace …
Ferrexpo's production process | Ferrexpo is the third
Ferrexpo is the third largest exporter of iron ore pellets in the world. Pellets are the most productive source of iron ore a steel mill can use. Watch this animation to learn more about Ferrexpo's production process.
Effect of adding limestone on the metallurgical properties of iron ore …
Acid iron ore pellets with 4.6 wt.% SiO 2 manufactured by Severstal Resources in Karelia were used in the investigations. Both test pellets were produced in a laboratory-scale pelletizing drum and fired in sample baskets set in the middle of the sintering belt on the same production line as commercial blast furnace pellets.
Creating Iron | HowStuffWorks
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. Liquid iron collects at the bottom of the blast furnace, underneath a layer of slag.
