Hindered-settling columns are simple to operate and have a large capacity, and have a great potential to be used for separation of particles in many areas including metallurgical and environmental fields. In this study, mathematical model of continuous hindered-settling process was constructed to evaluate the effects of several operating parameters and to find optimum operating condition and design. The model was based on the convection-diffusion equation and the hindered-settling equations. To calculate volume balance of solid a finite difference solution scheme was applied. Simulations were carried out to evaluate column performance for several operating parameters, such as dispersion, teeter water flowrate, feeding rate, etc.
