In the first section, methods of gravity concentration of gold-bearing ores and gravity equipment are reviewed. Particular attention is given to centrifugal concentrators (Knelson, Falcon, Multi-gravity separator (MGS), Kelsey, and Itomak), capable of extracting not only coarse but also very fine gold particles.
The Humphreys Spiral Concentrator is a simple, efficient gravity concentrator which effects a separation between minerals of the proper size range that have sufficient difference in their specific gravity.
Gravity concentration methods separate minerals of different specific gravity by their relative movement in response to gravity and one or more other forces, the latter often being the resistance to motion offered by a viscous fluid, such as water or air.
The present contribution aims to point out that a new different type of waste such as the slag resulted from the gold-bearing electrolytic mud smelting may be capitalized using gravity separation on Gemini table and Knelson concentrator, respectively. Metal recoveries up to 90–92% Au and 46–60% Ag, respectively, were obtained on Gemini table.
Our gravity concentration equipment provides the most effective solution in the field of gravity separation for industry-best recovery of gold and other precious metals. Designed for versatile operation, it suits many applications and fits any circuit size.
Gravity concentrators use the same principles of gravity separation at higher velocities. While conventional gravity separation happens at one G force, the Falcon SB uses up to 200Gs to concentrate microscopic particles as small as 20 microns. The same principles apply, just at a smaller scale. Dense particles will settle first, and light ones ...
Principles and Methods of Gravity Separation. Gravity separation processes can be broadly categorized into four main types:-Heavy medium separation (H.M.S. Baths, cyclones, etc.) Stratification in a pulsed or moving dense bed (Jigs). Film sizing with a thin flowing liquid film (Vanners, frames, etc.)
Falcon concentrators as enhanced gravity separators have been developed for the sharper separation beneficiation of finely disseminated ores based on their specific gravity differences.
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.

Gravity separation technologies other than Falcon concentrator have also been tested on ultrafine coal cleaning. Honaker et al. [ 21 ] used a single-start spiral to study ultrafine coal cleaning and the spiral concentrator was found to be effective in cleaning coal as fine as 44 μm. Ççek et al. [ 22 ] combined a Multi Gravity Separator with ...
A gravity concentrator namely "vibrating table" has been developed with the objective of increasing the product quality of density based physical separation processes. The system is mainly composed of a vibration unit, an inclined chute, TW and WW jets. ... Gravity separation of minerals is based upon the difference in specific gravity ...
The difference between a gravity concentrator and the other gravity separation devices previously discussed is the ability to increase the forces on the mineral particles that improve the particles' settling in a water medium. Instead of relying on one G force (the force of gravity), a spinning device, like a centrifuge, can increase the ...

As the most simple gravity separation technology, and arguably the most efficient, spiral concentrators have long played an important role in minerals processing. The spiral concentrator is one of the most effective, low-cost devices for the gravity beneficiation of ores. Manufactured from lightweight, corrosion and abrasion resistant materials ...
Falcon concentrators as enhanced gravity separators have been developed for the sharper separation beneficiation of finely disseminated ores based on their specific gravity differences.
Gravity separation is one of the oldest techniques used for separating minerals and relies on the differential settling of particles in a fluid medium (Clifford, 2009). ... 1999, Das and Sarkar, 2018, Falconer, 2003). As a typical centrifugal gravity separator, the Knelson concentrator (KC) has been widely used to recover gold and platinum ...
The utilization of mining and industrial wastes is gaining importance worldwide as it is a potential resource of many valuable minerals. The present study is focused on the separation of the fine and ultra-fine size scheelite particles present in the gold mine tailings using a Falcon advanced gravity concentrator.
Compact gravity concentrator designs increase available floor space and lower footprint; Gravity feed slurry distributors available (up to 36 feeder pipes) ... gravity concentrators improve the efficiency of executing tougher separation applications. Our gravity concentrators are built with fibreglass and polyurethane, providing a long, minimal ...
The devices used for gravity separation in mineral processing include gravity concentrators, jigs, and more. Which one should you choose?
Spiral Concentrators (Flowing Film) Separation by density occurs as a result of primary flow and circulating secondary flow patterns that are created as the feed slurry travels along an elongated helical trough surface that spirals downward around a central axis.
Outside grinding circuits, Falcon SB Gravity Concentrators are also used for precious metal separation from aggregate or placer deposits. Falcon SB Gravity Concentrators are known as Semi-Batch Gravity Concentrators because they continually accept feed during the run cycle, but only produce mineral concentrate during periodic rinse cycles.
