192 pagesIn this work we have been interested in the chemical exchange and mass transfer between minerals and aqueous fluids during a process which associates chemical reactions and transport. Our application concerns skarns type rocks composed of garnet or pyroxene minerals. First we set the problem in its thermodynamical context and we present a solution model for each phase. Second, we present three methods for deriving the isotherm function (from the writing of chemical potentials equality for the components in the fluid and in the solid phases or using equilibrium or exchange constants). The transport model has been obtained by expressing an isovolumic mass balance or by restricting to a mass balance within the fluid phase. Using some ...
