Define a handling target
Set the target against transport, stockpiling, smelting or downstream process needs—not a generic brochure value.
Mineral concentrate filtration
Concentrate Dewatering with Vacuum and Ceramic Disc Filters
Evaluate vacuum and ceramic disc filters for mineral concentrate dewatering, including feed testing, cake moisture, filtrate quality and equipment sizing.

Start with the Feed, Product and Water Balance
Concentrate dewatering sits between beneficiation and storage, transport or downstream processing. The correct solution protects valuable solids while producing a cake that the next operation can handle consistently.
Retain valuable fines
Cloth or ceramic media must balance throughput with acceptable solids loss and filtrate reuse.
Match the production schedule
Size duty and installed availability around normal and peak dry-solids flow.
Selection boundary
Concentrates with excessive ultrafines, difficult cake release, unstable upstream chemistry or a demanding wash duty may require additional testing or another filtration route.

Practical answers
Frequently Asked Questions
Use these answers to prepare a useful discussion with BOYUN. Final equipment selection still depends on project data.
Why is representative slurry data required?
Mineral names do not define filterability. Particle-size distribution, mineralogy, clay, reagent chemistry, feed solids and temperature can change cake formation, permeability and release. Use the filterability test process when performance is commercially important.
What information should be sent for a preliminary review?
Provide duty, mineral, dry throughput, feed solids, particle size or P80, target moisture, operating hours, elevation and available utilities through the disc filter quote page.
Does BOYUN guarantee cake moisture from a mineral name?
No. A responsible target must be tied to representative feed data, test conditions and an agreed equipment and operating basis.
Define the Next Engineering Step
Share the slurry, dry throughput, feed solids, particle size and target cake moisture. BOYUN will identify missing data and recommend testing, sizing or a suitable filter configuration.
