Thermodynamic Principles are applied to the ore extraction process. Gibbs energy is the most important term used to explain the thermodynamic principle. Gibbs equation is given below:

ΔG = ΔH - TΔS

ΔG is the change in the Gibbs energy

ΔH is the change in the enthalpy.

T is the temperature

ΔS is the change in the entropy.

ΔG = -RT lnK

K is the equilibrium constant.

R is the universal gas constant

Ratio of equilibrium concentrations of reactants and products will give equilibrium constant K. When a reaction moves from reactants to products, products are present in excess and equilibrium constant will be positive. But when reaction moves from products to reactants, equilibrium constant will be negative.

Answer 2

In using thermodynamic principle of metallurgy, we apply the concepts of thermodynamics such as Gibb's energy (ΔG) and entropy (S) to the principles of extraction of different metals.
