Jan 14, 2020· Methods for manufacturing steel have evolved significantly since industrial production began in the late 19th century. Modern methods, however, are still based on the same premise as the original Bessemer Process, which uses oxygen to lower the carbon content in iron.
In limestone calcination, a decomposition process, the chemical reaction is CaCO 3 → CaO + CO 2 (g). The standard Gibbs free energy of reaction is approximated as ΔG° r = 177,100 − 158 T (J/mol). The standard free energy of reaction is 0 in this case when the temperature, T, is equal to 1121 K, or 848 °C. Oxidation. In some cases, calcination of a metal results in oxidation of the metal.
