Experimentally observed dissolution rates of minerals in an aqueous solution are determined by surface reaction rates, mass transport by molecular diffusion through a diffusion boundary layer (DBL) and the morphology of ...
Empirical rate equations such as R=k(1-c/ceq)n in the dissolution of minerals are common in nature, e.g. limestone. The quantity c is the concentration of a major ion contained in the mineral, and ceq its concentration at ...
The effective dissolution rates of gypsum are determined by mixed kinetics, where the rate constants of dissolution at the surface and the transport constant of molecular diffusion of dissolved material are similar. To ...
