Abstract

In this study, the dissolution kinetics of magnesite mineral with Cl2 gas in aqueous media were investigated. The effects of reaction temperature, particle size, solid-to-liquid ratio, gas flow rate and stirring speed on the dissolution process were determined. It was observed that the dissolution of the magnesite mineral increased with increasing reaction temperature, gas flow rate and stirring speed and with decreasing particle size and solid-to-liquid ratio. By analysis of the experimental data using heterogeneous kinetic models, it was determined that the dissolution process is controlled by resistance of the chemical surface reaction for range 12°-40°C and film diffusion for range 40°-70°C. © 1999 Elsevier Science B.V.
