• Falcon UF Gravity Concentrator Features

    Ultra fine mineral recovery has been a mining industry goal for many years. Thanks to the Falcon UF Gravity Concentrators, there is now a way to economically recover and upgrade particles as fine as three microns. The primary objective of the Falcon UF Gravity Concentrator is to scavenge ultra fine mineral particles that are typically rejected from mining plant processes as slimes. Some of the machine’s other features are:


    • The industry’s most enhanced gravity concentration technology for meaningful fine particle recovery
    • Can operate anywhere from 50 to 600 Gs
    • Greater than 95% mechanical availability
    • Advanced wear materials and a modular design decrease downtime and maintenance costs


    • Recovers particles finer than 10 microns
    • Low maintenance costs (even lower than Falcon SB’s)
    • Parts costs are expected to be less than $0.01 USD per ton treated
    • Concentrate can be cleaned to saleable grades


    • No process water required
    • Small footprint
    • Extremely low operating costs
    • Fully automated, “one touch” operation, minimizes offline time and offers the highest mineral concentrate security

  • FAQs

    It’s groundbreaking technology is very new, what about its mechanical robustness?

    Sepro Mineral Systems’ Falcon UF Gravity Concentrator machines run on mechanical platforms that have been proven over almost two decades in plant environments.

    What do your model numbers mean?

    The model prefix designates the machine type. The suffix is the approximate concentrating surface area of the machine in square inches. A UF1500 Gravity Concentrator is batch unit with approximately 1500 in² of concentrating surface area.

    How sharp a separation does the Falcon UF Gravity Concentrator make?

    UF Gravity Concentrators are capable of producing extremely high grades of concentrate through multiple concentrating stages. Concentrating ratio at each stage is variable according to mineral, but is usually about 4-10.

    What top size should be fed to Falcon UF Gravity Concentrators?

    Top size is 38 μm. Falcon UF’s are specifically designed for recovery of extremely fine minerals, down to 5 microns and less. If your separation involves target minerals coarser than 1 mm, it would be best to look at other technologies for the coarse fraction.

    Are there ‘gravity-only’ flowsheets available?

    Yes, Sepro Mineral Systems has developed unique flowsheets to help clients achieve previously unobtainable recoveries without using any reagents such as cyanide.
