How a Thickener Works Previous Next Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids The early methods of thickening employed plain flat-bottomed tanks into which the pulp was fed until the tank was full The solids were then allowed to settle as long as required the top liquid
As the tailings slurry is collected in the compound the water separates from the heavier sand and silt particles and is collected at the surface The tailings pond water is then recycled back into the operation for reuse and the tailings may be reclaimed so as to minimise the impact on the environment
