Abstract
The thermal behavior of a purified galena in a chlorine surrounding was det ermined. The kinetic of the chlorination of galena and the stoichiometry of this reaction between 723 to 973 K (450 to 700 degrees C) were measured by thermogravimetry. The microstructural characterization of the solid residu es were determined by SEM, EDXS and XRD. The Delta H-vap of the produced le ad chloride volatilization was obtained by the application of Clausius-Clap eyron equation considering the process in an equilibrium state.
