Abstract

Weight loss measurements at different T and PCO2 during experimental investigations of the dissolution kinetics of eight samples of dolomite permitted recognition of a two-stage process. During the first stage, which is brief, the surface composition of the dolomite becomes enriched with the MgCO3 component and the CaCO3 component dissolves faster. In the second and more important stage both components of the solid are released stoichiometrically, described quantitatively by three parallel consecutive forward reactions and one significant backward reaction. Dissolution rates are apparently more dependent on crystallographic order than on compositional variations. -M.S.
