The Total solution for NCERT class 6-12
Write down the reactions takingplace in different zones in the blast furnace duringthe extraction of iron.
During the extraction of iron,the reduction of iron oxides takes place in the blast furnace. In this process,hot air is blown from the bottom of the furnace and coke is burnt to raise thetemperature up to 2200 K in the lower portion itself. The temperature is lowerin the upper part. Thus, it is the lower part where the reduction of ironoxides (Fe2O3 and Fe3O4) takes place.
