• Solid-Liquid Separation - an overview ScienceDirect

    The flowsheets in Figures 18.118.3 illustrate how liquidsolid separation fits into carbon-in-leach (CIL), carbon-in-pulp (CIP), and MerrillCrowe circuits, respectively. In addition, heap leach, column leach, and gravity circuits also need to have liquids separated from solids, and there are many variations of the flowsheets presented.
