yes its absolutely like this
by the way how is the production of iron in the blast furnace
iron production
Raw material Iron ore coke lime stone
temperature 1900*C
1) C+O2= CO2
2) Co2+C=2CO
the CO2 rises n reacts with more C to orm C0
3) Feo3 +2co= 2fe +3co2
the Co reduced the iorn ore at the top of the furnace to molten iron metal (pig iron) which fallls to the bottom of the furnace n Co2 escapes freom the top as a waste gas
4) limestoen is present to help remove impruties .the main impuritty is sand (silicon oxide) inside the furnace the limestone decompses tof orm Cao n co2
CaCo3=CaO +co2
5) the co2 whch is produces reacts with the hot coke yo produce more Co but the lime combines with the sand impurity to form a molten slag alled Calcium siliate
CaO+ SiO2=CaSiO3
the slag bcuz its molten runs to the bottom of the furnace asd its lighter then molten iron thus it floats on the surface n can be tapped off
