Abstract :
A comprehensive kinetic study of the xanthate ions sorption on CuS was performed as a function of different experimental conditions of temperature and concentration. Adsorption kinetics experiments indicated that xanthate adsorption onto the CuS reached steady-state within approximately seven and ten minutes from the start of the experiment in case of high and lower concentration of xanthate anions respectively. Legregran s first order equation was applied for the determination of the rate constant. Temperature had a positive effect on kinetics of the process and from the temperature dependence of the rate constant, energy of activation was calculated.
