Wet beneficiation of minerals necessarily requires removal of large amounts of water—typically contaminated—before further processing of the concentrated ores can be carried out. Often such concentrates are transported over large instances by ground or sea transport. For economic reasons dewatering/drying are essential unit operations. …

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 ...

How TenCate Geotube® Dewatering Technology Works. Dewatering with TenCate Geotube® technology is a three-step process: Step 1: Filling. Sludge (slurry material) is pumped into the TenCate Geotube® container. Environmentally-safe polymers are added to the sludge, which makes the solids bind together and water separate.
Mines cannot operate without a robust and flexible dewatering strategy. As no two mines are the same, each site's dewatering requirements will vary, with environmental and geological considerations as well as local climatic variations that present unique challenges. Variations in weather conditions can have a significant effect on open-pit mining in …

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.
