One order of steel; hold the greenhouse gases | MIT News ...
· The prevailing process makes steel from iron ore — which is mostly iron oxide — by heating it with carbon; the process forms carbon dioxide as a byproduct. Production of a ton of steel generates almost two tons of CO2 emissions, according to steel industry figures, accounting for as much as 5 percent of the world's total greenhousegas emissions.

Processes and Procedures in the Extraction of Iron ...
· The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.

Iron | Introduction to Chemistry
Iron(II) compounds tend to be oxidized to iron(III) compounds in the air. Iron reacts with oxygen in the air to form various oxide and hydroxide compounds; the most common are iron(II,III) oxide (Fe 3 O 4) and iron (III) oxide (Fe 2 O 3). Iron(II) oxide also exists, although it is unstable at room temperature.
