One of the major aspects that makes long distance concentrate pipeline operations a significant challenge in the product dispatch process are system shutdown and startup procedures. After shutdown, complex topographies marking the existence of positive and negative sloping sections induce solids migrations towards low points. A remarkable feature of this gravity induced solid-liquid flow is the existence of a self-induced segregation process, which ultimately results in a vertical size and/or density distribution at each cross-sectional plane of the tube, where the overall sedimentation process along with the final solids organization depend strongly on tube geometry and slurry properties. In this work, the relevance of the latter aspect is studied in the light of set of experiments. Using pairs of equal density particles, including glass beads with different characteristic sizes and concentrations, final sedimentation patterns of bi-disperse mixtures at different relative were measured. Experiments, done in a set of clear Perspex were video recorded from the start of sedimentation until the formation of the settled bed. Final depositional patterns have been observed to evolve from complete stratification to partial ones with vertical intrusions of one species into another, depending on both the relative concentration of each particle type and the total volumetric concentration.
