Abstract: A process for separating a mixture of materials using a segregation media within a vessel having a central baffle structure which shuggles the mixture by oscillating the baffle structure at a frequency and amplitude. The mixture of materials may have overlapping densities with the segregation media having a density within the overlapping region. Polymers PE and PP may be separated in flake form. For a mixture of materials of differing densities, water may be the segregation media. Shuggling is combined with controlling the flow of water through the vessel at a set velocity. Embodiments are described for separating plastics and mineral ore.
