Define the Tailings Circuit, Not Only the Filter
Gold tailings vary with ore, grind, leach or flotation route and residual chemistry. Filtration must be assessed within the site’s environmental, water and residue-management 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
Some fine, clay-rich or low-permeability tailings will not meet capacity or handling targets under vacuum. Alternative conditioning, a different filter technology or pilot work may be required.

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.
