Abstract

Experimental studies of the kinetics of dissolution of gypsum-anhydrite rocks in water (25 °C; P = 0,1 MPa) made it possible to formulate a process model in the form of a system of equations for the kinetics of dissolution of gypsum and anhydrite (of the first and second order, respectively). The calculated values turned out to be more comparable with the experimental data, taking into account the common-ion effect on the solubility of gypsum and anhydrite, and changes in their values of the specific reaction surface.
