The reaction that does NOT take place in a blast furnace between 900 K to 1500 K temperature range during extraction of iron is?
The reaction that does NOT take place in a blast furnace between 900 K to 1500 K temperature range during extraction of iron is?
FeO + CO \(\to\) Fe + CO2
C + CO2 \(\to\) 2CO
CaO + SiO2 \(\to\) CaSiO3
Fe2O3 + CO \(\to\) 2FeO + CO2
The Correct Option is D
Solution and Explanation
Fe2O3 + CO → 2FeO + CO2
This reaction does not take place at between 900 K to 1500 K temperature range during extraction of iron.
It takes place at between 500 K to 800 K temperature range.
So, the correct option is (D): Fe2O3 + CO \(\to\) 2FeO + CO2

What are Ores and Minerals?
Minerals are the naturally occurring, homogeneous inorganic solid substances. They are having a definite chemical composition and crystalline structure, hardness and color. For example, copper pyrite, calamine, etc.
Impurities in an ore are called gauge. The removal of a gauge from the ore is called concentration ore.
Several steps are involved in the extraction of pure metal from ores. Major steps are as follows –
- Concentration of the ore
- Isolation of the metal from its concentrated ore
- Purification of the metal
