Falcon C Series FAQ
What is Falcon C technology?
Falcon C (Continuous) technology is a family of truly continuous enhanced gravity concentrating machines that has been proven in commercial applications to be able to withstand 300G concentrating fields while delivering superior metallurgical and mechanical performance at throughputs in excess of 100 t/h. Each machine consists of a single moving part. A feed stream enters the machine and is divided into high and low density fractions. Proportioning of exit streams is continuously variable by the operator.
Does this technology consume process water?
No. Model C Falcon Concentrators require no fluidization water. The dense fraction is produced at pulp densities usually in excess of 70% solids and is well deslimed. The light fraction pulp density is very close to that of the incoming feed.
What is the maximum capacity of your continuous range?
Sepro has commercial installations with unit capacity over 100 t/h.
What are the operating costs?
The simple and robust design of the Falcon C means that unit operating costs are the lowest in the industry, normally a few cents per tonne treated.
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 C4000 is a continuous unit with approximately 4000 in² of concentrating surface area.
How sharp a separation does the Falcon C make?
Falcon C's are normally capable of concentration ratios in the order of 4. Fortunately, it is very easy to configure Falcon C's in rougher/cleaner or even rougher/cleaner/cleaner configurations. This gives the mineral-processing Engineer the opportunity to achieve both very high recovery and very high grade with a single, simple, proven technology.
What top size should be fed to Falcon C machines?
Top size is 1 mm. Falcon C's are specifically designed for recovery of very fine minerals, down to 20 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.
How long has Sepro Mineral Systems been in business?
Since 1987.
What is the difference between the Falcon SB and C machines?
Falcon SB's are batch-type concentrators that use fluidization water to obtain a high-grade concentrate and a mass pull to concentrate << 1%. SB's are used primarily for the recovery of precious metals in the free, metallic state. The Falcon C's, on the other hand, do not require any fluidization water and are mainly used for pre-concentration and scavenging where high mass recoveries are required. C machines can pull up to 40% of the feed mass as concentrate.
What are the major industries that Sepro Mineral Systems technology is used in?
Falcon C: Au, Ag, Ta, Sn, Coal, Iron ore, Titanium sands and Cr.
Falcon SB: Au, Ag and PGM's.
Falcon UF: Ta, Sn, Coal, Iron ore, Titanium sands and Cr.
What is Sepro Mineral Systems' commitment to servicing their clients across the globe?
Sepro has a global network of representatives who are as committed to service and support as Sepro itself. Please refer to for the contact information for your closest representative.
What operating availabilities does Sepro Mineral Systems equipment attain?
Sepro Mineral Systems will guarantee mechanical availability >95% as long as equipment is installed and maintained according to our recommendations.
How do you calculate the "G" forces produced by a centrifugal field?
Centrifugal Field in G's = Rotor Diameter (inches) x RPM2 ÷ 70471.
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.
