In this study the dissolution kinetics of phosphate rock with Cl2 gas in aqueous media were investigated. The effect of particle size, solid-to-liquid ratio, gas flow rate, reaction temperature and stirring speed on the dissolution process were determined. It was observed that the dissolution of the phosphate rock increased with increasing gas flow rate and stirring speed and with decreasing particle size and solid-to-liquid ratio. Increasing reaction temperature increased the dissolution slightly between 12°C and 30°C and decreased it between 40°C and 80°C. By analysis of the experimental data using heterogeneous kinetic models it was determined that the dissolution process is controlled by diffusion through the fluid layer.
