The Dorr-Oliver Paste Production
Storage Mechanism (PPSM) is a
unique device and process designed
to “flash thicken” solids to paste
consistency. The paste viscosity is
controlled to permit storage.
Paste thickeners maximize the
efficiency of a range of applications
such as:
• Dry stacking of tailings
• Underground paste backfill
• Counter-current decantation (CCD)
• Autoclave leach feed
• Maximum water and chemical
recovery
• Increase downstream process
efficiency
