years, solutions in which the dewatering of tailings can be achieved using a less risky method than bulk storage in dams. In addition, the liquid fraction from the dewatering process can be reused immediately a clear benefit in areas where water is a scarce resource.
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.
tailings porewater has the electric conductivity of 8,000 Scm, which is considered favourable in terms of power consumption for EK dewatering. 3. The zeta potentials of the tailings before and after EO tests are stable in the pH range of 49, indicating EO dewatering would be effective in tailings

Solutions FLSmidth is a world leader in comprehensive unit operation based
Nov 18, 2019 The foremost 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. This can also minimise power requirements.
Sep 11, 2020 Four Kinds of Tailings Dewatering Methods. Tailings dewatering is a new type of tailings dry heap treatment, which usually adopt dewatering equipment to fully extrude the tailings slurry discharged from the ore dressing into dry flaky tailings cake, and then transport to the tailings dry yard for layered stacking by belt conveyor.
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.
