Question

The smelting of iron in a blast furnace involves, which of the following process(es)?
A. Combustion
B. Reduction
C. Slag formation
D. Fusion

Answer 1

Correct Answer - A,B,C,D
`C+O_2toCO_2`(combustion zone)
`C+CO_2to2CO` (fusion zone) , `FeO+CtoFe+CO`(fusion zone )
`CaO+SiO_2 to CaSiO_3` (slag formation zone ) , `FeO+CO to Fe + CO_2` (slag formation zone )
`3Fe_2O_3 + CO to 2Fe_3O_4 + CO_2` (reduction zone) , `Fe_3O_4 + CO to 3FeO +CO_2` (reduction zone)
