The Extraction of Metals from Their Oxides and Sulphides.

Peer reviewed

Price, Alun H. – School Science Review, 1980

Briefly describes the application of thermodynamics (system at equilibrium) to the study of the extraction of metals from their oxides (dynamic situation). It is more relevant to study the temperature variation of the equilibrium constants of the reaction than to study the free energy approach. (Author/SK)
