Lead-Zinc Tailings Dewatering with Disc Filters
Assess disc filtration for suitable lead-zinc tailings, including slurry preparation, capacity, cake moisture, water recovery and dry-stack handling needs.

Define the Tailings Circuit, Not Only the Filter
Lead-zinc tailings duties can change with ore blend, grinding and flotation chemistry. The filter basis must include representative variability and site-specific water and residue controls.
Create material the next step can handle
Link moisture and consistency to conveying, stacking or other placement.
Design for variability and upset
Include difficult feed, downtime, off-spec cake and water-management scenarios.
Application boundary
Vacuum disc filtration is a candidate only where the conditioned feed forms a permeable cake at viable flux and releases consistently. Testing must include the limiting fines or clay condition.

Practical answers
Frequently Asked Questions
These answers support project preparation; the final recommendation depends on the actual duty.
Why is representative slurry data required?
Mineral names do not define filterability. Particle-size distribution, mineralogy, clay, reagents, solids and temperature can change cake formation, permeability and release. Use filterability testing when results matter commercially.
What should be sent for a preliminary review?
Provide dry-solids throughput, feed solids, particle-size data, target cake moisture, operating schedule, elevation and available utilities through the quote request.
Can BOYUN promise cake moisture from the mineral name alone?
No. A defensible target must be tied to representative feed data, test conditions, equipment scope and an agreed operating basis.
Define the Next Engineering Step
Share the feed, throughput, operating target and site constraints. BOYUN will identify missing information and recommend testing, sizing or the appropriate equipment scope.
