✦ Synopsis

The dissolution of dolomite in hydrochloric acid was studied with the aid of a rotating disk system. At 25°C the dissolution process is surface reaction rate limited even at low disk rotation speeds. As the temperature is increased to 100°C the dissolution process approaches diffusion limitation even at relatively high (500 rpm) rotation speeds. The rate of reaction was found to be proportional to a temperature dependent fractional power of the hydrochloric acid concentration. Analysis of the experiments suggests that adsorption of hydrogen ion (described by a Freundlich isotherm) on the solid dolomite surface and subsequent reaction of the adsorbed hydrogen ion with the solid dolomite matrix is the reaction mechanism.

The dissolution of a potassium and a sodium feldspar in hydrochloric-hydrofluoric acid mixtures was studied in a rotating disk system at 25 and 100°C under a pressure of 40 psig. Under these conditions, the dissolution rate is limited by the rate of reaction of the acids with the solid surface. The
