The dissolution of Icel-Aydincik dolomite in aqueous hydrochloric acid solution was investigated with respect to the effects of acid/dolomite mole ratio, solid/liquid ratio, particle size, stirring speed, time and temperature. It was observed that solubility of the dolomite ore increased with increasing acid/dolomite mole ratio, stirring speed, period of time, temperature, and with decreasing solid/liquid ratio and particle size. A kinetic model was applied to describe the dissolution and to analyse the kinetic data. By analysis of the experimental data, it was determined that the leaching process was controlled by the chemical surface reaction. The apparent activation energy of the leaching process was found to be 31.98 kJ mol-1.

Keywords: Dolomite dissolution, dolomite dissolution kinetics, dolomite leaching, dolomite leaching kinetics
