Mine Water Management and Recycling: The Importance of Thickener
A thickener is a device that filters liquids from solids. Thickeners were first used in the mining business in 1905. ... Thickeners are commonly used in hydrometallurgical operations to produce concentrate from raw ore and to enhance the solid content of the concentrate mixture (concentrate + treatment water) so that the highly-dense slurry can ...

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.

Solid – Liquid Separation – Thickening
In general, 75–80 % of the water can be separated and removed by thickeners. For further water removal, filters are used where in excess of 90% of the water can be removed. The thickener operation can be a batch or continuous process, with either co-current or counter-current flow of underflow and overflow slurries.
