Another way to create steel from pig iron is the Bessemer process, which involves the oxidation of the impurities in the pig iron by blowing air through the molten iron in a Bessemer converter.The heat of oxidation raises the temperature and keeps the iron molten. As the air passes through the molten pig iron, impurities unite with the oxygen to form oxides.
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 useful components from the waste materials such as slag. What happens in the Blast ...

Apr 04, 2012· D. Zhu, in Iron Ore, 2015. 16.4 Summary. The BF ironmaking process is currently the dominant process for providing steelmaking raw materials worldwide. However, the BF process relies heavily on metallurgical coke and involves cokemaking and sintering operations, which often attract serious environmental concerns.
iron processing - iron processing - Iron making: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.

The manufacture of iron ore involves the process of reduction. Important ores of iron: Haematite, Magnetite. Previous Question Next Question
Jun 06, 2017· The first step in the steel manufacture begins at the blast furnace. To separate iron from iron ore coke (substance when gas is taken out of coal), limestone and dolomite are charged into the blast furnace. Temperature raised to 1600oF. This high temp causes the coke to burn and melt the iron. This red hot iron drained at an opening at the base of the furnace.
manufacture of iron from iron ore involve the process of The Modern Steel Manufacturing Process Ironmaking the first step in making steel involves the raw inputs of iron ore coke and lime being melted in a blast furnace The resulting molten ironalso referred to as hot metalstill contains 445 carbon and other impurities that make it brittle.
The European iron workers knew the Easterners had better iron, but not the processes involved in fashioning stronger iron products. Entire nations launched efforts to discover the process. The first known European breakthrough in the production of cast iron, which led quickly to the first practical steel, did not come until 1740.
(3) Sponge Iron Process: As the name implies, the spongy iron is obtained by the reduction of lumpy iron ore or iron ore pellets from the oxide form into the metallic state. The iron content of the product so obtained varies from 90% to 94% and the balance represents the traces of gangue and residual iron …
Making steel. Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route.
