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.

Blast Furnace Slag Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast furnace. When the metallurgical smelting process is complete, the lime in the flux has been chemically combined with the aluminates and silicates of the ore and coke ash to form a non-metallic product called blast furnace slag.

Both had square cross sections, and the main changes required for blast-furnace operation were an increase in the ratio of charcoal to ore in the charge and a taphole for the removal of liquid iron. The product of the blast furnace became known as pig iron from the method of casting, which involved running the liquid into a main channel connected at right angles to a number of shorter channels.

Iron making basics Making iron is the first step in producing steel Iron should be produced of consistent quality. C= 4.55 %, Si =0.0.4 1..0%, Mn = 0.2-0.3%, S= 0.015- 0.040%, P=0.080-0.090%, Rest Fe. Blast furnace is a reactor to produce iron. Ore reaches molten state and gets separated physically due to density from gangue and impurities.

Some examples of ferrous metals would be mild steel, cast iron, high strength steel, and tool steels. Examples of non-ferrous metals would be copper, aluminum, magnesium, titanium, etc. To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added.

AbstractTraditionally, iron ore has been reduced with coke in a blast furnace and the hot metal product of the blast furnace containing carbon, manganese, silicon, sulphur and phosphorous, was subsequently refined in a steelmaking furnace. During ironmaking as well as during steelmaking, significant amounts of slag are produced. Two decades ago, more than 13 million tonne (mt) of blast furnace

Blast Furnace Slag Material Description ORIGIN In the production of iron, iron ore, iron scrap, and fluxes (limestone and/or 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.

GGBFS is obtained as a by product in the extraction of iron from it ore. The process of extraction of iron is blast furnace. The slag that is obtained on the iron ore is separated and cooled down slowly, which results in the formation of nonreactive crystalline material.
