Steel Metallurgy – a complex topic if there ever was one. So what are the basic chemical reactions associated with manufacturing steel?
Iron ore, coke (carbon, coal) and limestone are fed into the blast furnace.
Essentially the chemical reaction is
3Fe2O3 + CO = CO2 + 2Fe3O4 which starts at 850F
Fe3O4 + CO = CO2 + 3 FeO which starts at 1100F
FeO + CO = CO2 + Fe or FeO + C = CO + Fe which starts at 1300F
The process of making steel is to remove the oxygen out of the iron ore by converting it to CO2.
But if you kill off coal mining, and also reduce emission of CO2, then you would need to also close iron ore mining and downstream steel/iron manufacturing process to remain consistent in reducing CO2 emissions
Reducing CO2 emissions thus entails not only killing off coal mining but also iron mining and terminating the iron age.
They are simply barking mad.
