Liquid–Solid Separation in Gold Processing
The flowsheets in Figure 18.1, Figure 18.2, Figure 18.3 illustrate how liquid–solid separation fits into carbon-in-leach (CIL), carbon-in-pulp (CIP), and Merrill–Crowe 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.
