Packed column jig has been demonstrated a number of promising results in processing iron ore, coal, chromite and other finely disseminated particulate materials. The packing materials in the jig divide the column into a large number of virtual cells. Each cell performs the similar separation action. A model about the movement of a particle in the packed column jig was derived to interpret the separation mechanism of particles in the virtual cell. A computer program was developed to simulate the particle movement in the jig based on the derived model, which can simulate the packed column jigging with different jig geometry, ore properties and operation conditions. It also allows a visual simulation of particles moving in the packed column jig. By analyzing the simulation results, the effects of jig cell dimensions, pulsating frequency, stroke length, particle size, mineral density, particle packing density in the jig, etc. were obtained.
