In the extraction of iron, the waste gas from the furnace is a mixture of
PH3 CO and CO2
CO and C
N2 , CO and CO2
PH3 and CO
Correct answer is C
the \(N_2\) from the hot air blast to burn the coke (48%), the \(CO\) (23%) and \(CO_2\) (21%) produced from the reduction of the iron ore \(Fe_{2}O_{3}\) by carbon (the coke) are the major components of the waste from the extraction.
