General Principles and Processes of Isolation of Elements ...

The process of extracting a metal by reduction of its oxide with carbon (in form of coke, charcoal or carbon monoxide ) is called smelting. Thermodynamic Principles of Metallurgy. We know, ΔG = ΔH – TΔS where ΔG is gibb's free energy, ΔH is the enthalpy change, ΔS is entropy change and T is the absolute temperature.
