Iron is extracted from iron ore in a blast furnace. 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. …
The blast furnace (BF) is the most energy-consuming and important reactor in ironmaking industries at present (i.e., conventional BFs) and in the near term (i.e., novel BFs) [1].In the BF process, iron ore and coke are loaded alternately at the furnace top, and hot blast is introduced into the lower part of the furnace along the circumference …
The blast furnace is a counter-current heat exchanger used to smelt iron from iron ore for steel production. Reactions inside reduce iron oxides to molten iron and separate impurities into a slag. The furnace operates at over 1500°C, using coke as the reducing agent and limestone as a flux.
Hint: We have to draw the diagram of the blast furnace used in the extraction of iron. It is used for the common ores like iron oxides to extract the iron with the help of reduction with carbon. The apparatus consists of many parts like hot air blast, tap hole etc. Design the blast furnace. Complete step by step answer:

Blast furnace. 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. Raw materials. Iron ore …
Limestone, coke and iron ore are added at the top. Hot air is blasted in front rom the bottom. The hot air burns the coke and makes carbon dioxide. Carbon dioxide reacts with more coke to form carbon monoxide. Carbon monoxide reacts with iron oxide and forms molten iron and carbon dioxide. The molten iron sinks to the bottom.

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 ...
In a blast furnace iron ore, coke, and limestone are constantly supplied at the top of the furnace; meanwhile hot are is blast into the bottom section of the furnace. Chemical reaction takes place throughout the furnace, since materials are moving downwards from top of the furnace. Final products from the blast furnace are molten …

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. Coke is a cheap and readily made reducing agent.
The use of coke with high reactivity in the ironmaking blast furnace (BF) has yet to be explored, and a thorough understanding is still required to clarify the effect of coke reactivity on the BF gas utilization efficiency. In this paper, a one-dimensional kinetic model of the BF is presented and the accuracy of the model is verified. The model is …
