A contact model based on the discrete element method (DEM) coupled with a simplified fluid model is used to describe the motion of particles during jigging. The 3D DEM model is able to predict the concentration of particles of each and individual particle types across the jig bed. The model is validated against experimental data collected from a properly instrumented and controlled pilot scale jig. The experimental results show a reasonably good agreement with the model predictions.
