Quick answer: A mining tailings dewatering filter press turns thickened tailings into a stackable cake of roughly 15–25% moisture, cutting the volume to be stored by well over half and recovering most of the process water. Large plates (1500–2000 mm), membrane squeeze and automatic cake discharge are standard where dams are restricted, water is scarce or dry stacking is required.

Buyer FAQ
How does a tailings filter press help mines?
It dewaters tailings to a dry, stackable cake, recovers process water and reduces or eliminates the need for a wet tailings dam.
What pressure does it operate at?
Up to about 2.0 MPa for very dry cake on fine mineral tailings.
What moisture does a tailings press achieve?
Typically 15–25% for dry-stack tailings, depending on particle size and clay content; membrane squeeze and air blow-down are used where the stack must be trafficable.
How is a tailings press sized?
On tonnes of dry tailings per day and the filtration rate measured on your sample. Large presses (1500–2000 mm plates) with automatic discharge are standard for continuous mine duty.
