Chamber Filter Press Dewatering Plant for Base Metal Tailings

Facing stringent environmental zero-liquid-discharge standards and water scarcity, our client required a robust dry-stack filtration system capable of processing 2,500 metric tons per day of zinc flotation tailings.

Metzix engineered two 1500mm x 1500mm recessed chamber filter presses equipped with automatic plate shifters, high-pressure core wash systems, and integrated cloth washing carriages. Auxiliary equipment included heavy-duty knife gate valves and cake collection transfer conveyors.

The dewatered cake moisture content achieved an average of 14.5%, enabling safe and compact dry stacking without requiring wet tailing storage facilities.

Key Results & Performance Metrics:

• Filter cake moisture reduced below 15%, ideal for surface dry stacking
• Process filtrate water clarity under 15 ppm suspended solids returned to mill
• Cycle duration optimized to 22 minutes total turnaround time
• Complies with highest global mine waste safety and ZLD benchmarks
