What is the equation of the exothermic reaction in a blast

In a blast furnace, which is generally used to obtain pure iron from its ore, the following reactions take place. Of these only the reaction between oxygen and carbon is exothermic. This reaction is responsible for increasing the temperature of the blast furnace so that the other reactions between the carbon compounds and iron oxide can take place.

Iron ore

Iron ore

Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil ".

2a. Extraction of Iron in a blast furnace. 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.

Hematite is also known as "natural ore". The name refers to the early years of mining, when certain hematite ores contained 66% iron and could be fed directly into blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. 98% of the mined iron ore is used to make steel.

Iron Ore Formation. Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.

Port Talbot Port Talbot in South Wales is home to one of three integrated iron and steel plants in the UK the other two are two are at Scunthorpe and Redcar. At these plants, Corus (formerly British Steel) converts iron ore into steel and, using high tech casting and rolling, produces intermediate steel shapes (blooms, billets etc). These are made into the final products by customers.

Hydrothermal Deposits Hot aqueous solutions are responsible for the formation of many ore deposits. Fluid inclusion research indicates most ore forming fluids range in temperature from 50C to 650C. Analysis of the fluid in inclusions has shown that water is the most important phase and salinities are often much greater than those of seawater.

The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron.

Slag and its Role in Blast Furnace Ironmaking IspatGuru

Aug 07, 2015The quality of hot metal obtained is dependent on the formation of the slag and its mineralogical transformations. A good quality slag is necessary for a quality hot metal. The slag is a mixture of low melting chemical compounds formed by the chemical reaction of the gangue of the iron bearing burden and coke ash with the flux materials in the charge.

The blast furnace. Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron(III) oxide, Fe2O3. The oxygen must be removed from the iron(III) oxide in order to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions.
