Dewatering in mineral processing is normally a combination of the above methods. The bulk of the water is first removed by sedimentation, or thickening, which produces a thickened pulp of perhaps 55 65% solids by weight. Up to 80% of the water can be separated at this stage. Filtration of the thick pulp then produces a moist filter cake of ...

Tailings are the byproducts of mineral processing, and they typically contain water. Dewatering the tailings helps reduce the volume of water, making it easier to store and transport them. Various dewatering techniques, such as filter presses, thickeners, and centrifuges, are used to separate the solids from the water in tailings management.
