Abstracts
The kinetics of the roasting of iron and copper sulfides in a pulsating layer was studied, and the kinetic parameters of the processes were determined. The determination of the order of the roasting reactions and activation energy in the MeS – Na2CO3 - O2 system is based on the differential method. Using the dependences of the degree of conversion of copper and iron sulfides in the reactor of the vibratory pulsating layer at a pulsation frequency of 50 Hz and a pulsation amplitude of 0,1 - 0,5 mm, the values of the apparent activation energy in the temperature ranges of 500 – 550 - 600 °C were obtained for FeS 1,60 - 1,64 and for Cu2S 1,44 - 2,41 J*mol. (CO2).
