This article discusses the process of ion exchange in a range of solids through interface-coupled dissolution-precipitation in the presence of an aqueous solution.
The equilibration of minerals in the presence of an aqueous fluid phase, with which it is out of equilibrium, has been described in terms of a number of potential mechanisms, specifically mainly either by solid state exchange of elements within the solid phase and the aqueous solution, or by interface-coupled dissolution-precipitation where equilibration is approached by the incremental dissolution of the parent solid and the coupled precipi-tation of a new solid. The conditions determining the equilibration mechanism can be defined by the specific chemical potential differences at the mineral interface, the kinetics of potential reactions, the solubility of the solid phase in the specific fluid and physical properties such as the mineral: fluid ratio as well as the surface area: fluid ratio, temperature and pressure. This review focusses on the mechanism of ion exchange in a range of solids by interface-coupled dissolution-precipitation in the presence of an aqueous solution.
