In this paper dissolution of dolomite ore, collected from Mersin/Aydincik in Turkey, was investigated under various experimental conditions in the presence of HCl acid. Particle size, acid/dolomite ratio, solid/liquid ratio, stirring speed, reaction time and temperature were also conducted to the determin the optimum experimental conditions. During the experiment, CO2 amount released from the dolomite was measured through the experimental apparatus to determine reaction orders and rate constants of the sample at the different temperatures by using the fractional life approach method. It was found that, reaction orders and rate constants, based on temperatures, changed from 1.505 to 1.339 and between 3.17 and 10.49 10–2 mol dm–3 sec–1 respectively. In addition, differences in reaction rate constants were examined with the Arrhenius equation and activation energy of the dissolution process was calculated as 16.69 kJ mol–1, which was consistent with the activation energies determined in literature.
