Residue Disposal
Disadvantages of Traditional Methods
Traditional methods for the disposal of bauxite residue and red mud such as trucking, conveying, or wet slurrying at low concentrations, have numerous operational and cost disadvantages associated with them. In addition to being unreliable, noisy, and inefficient, non-pipeline solutions produce environmental hazards due to dust and groundwater seepage.
HCSD is the Economical Answer
PSI specializes in High Concentrated Slurry Disposal systems (HCSD), which have experienced increased popularity for the disposal of red muds. This innovative technology provides a more economical solution due to the reduced water in the slurry stream and the ability to employ central ramp or side hill discharges, which avoid the need to raise perimeter dams and thus extend the life of disposal sites.
Compelling Ecological Advantages
Because thickened mud is not subject to run-out, and seepage into groundwater is virtually eliminated, HCSD systems designed by PSI provide long-term stability. This also means that the ground can be easily covered for restoration of the natural environment, thus emphasizing environmental responsibility, a core value at PSI.
