THE KINETICS OF FERRIC CHLORIDE LEACHING OF SPHALERITE IN THE MICROWAVE FIELD
(Kunming Institute of Technology, Kunming 650093, China)
Abstract: The kinetics of ferric chloride leaching of sphalerite in the microwave Field has being studied in this paper.According to the experimental data, the rate of dissolution of sphalerite microwave irradiation heating is faster than that with conventional heating. The dissolution of sphalerite in the microwave field was investigated in different condition of temperature, concentration of FeCl3 and particle size and a nonisothermal kinetic equation has being obtained.
Key words: Microwave field, ferric chloride> sphalerite, kinetics of leaching
