Tailing Dewatering. Tailings are fine-grained residues in the form of sludge produced during the processing of ores and minerals. In ore mining operations, tailings are generally stored in large tailings dams and settling basins or sludge ponds. These exposed tailings may cause run off or seepage. This will adversely affect the environment.

Feb 28, 2020 A system of tailings dewatering based on a designed semi-industrial apparatus was constructed, as shown in Figure 3. As indicated in the figure, the tailings slurry from the ore-dressing plant of XTM was transported to a buffered mixer (XB-1000, Shicheng, Jiangxi) by self-flowing. The RTS was transported to the mixer at the same time.

Dewatering tailings prior to disposal may prove a good alternative since, if correctly designed, a reasonably steady flow with consistent reduced water content can be expected from the thickeners or filters. Nonetheless, there is a perception that dewatering could add significant capital expenditure and complexity to the project.

Oct 20, 2020 The most important benefit of dewatering tailings is the reduction of water that needs to be transported from a process plant to a tailings storage facility (TSF). Reduced water content means tailings' slurry volume is decreased, allowing for smaller pipelines and pumping equipment to be used, which can minimise power requirements.
