FALCON Semi-Batch (SB) concentrators are specifically designed to recover precious metals that occur in the free, metallic state. This type of application requires very high concentrating ratios and consequently very small mass yields to concentrate, usually << 0.1%. Continuous Falcon Concentrators (C) are used in applications where a ...
Multotec has designed and optimised both single (SX4) and double stage (MX7 and SX7) Coal Spiral Concentrators to treat a size range of 2.0 to 0.1 mm. Gravity separation of fine heavy minerals in the size range 1.5 to 0.04 mm may be conducted on spiral concentrators. The popular Pipe Launder and Product Collection Launders are now …
The Falcon's high g-force power allows for increased settling velocity of even the finest particles. This leads us to the second big difference between Falcon Gravity Concentrators and other products: 2. The size of the particles they can recover. Each Falcon can recover very fine particles, but the Falcon UF can recover the finest particles ...
Finally, gravity concentration provides the versatility for treating a wide particle size range. Using pre-concentration as an example, devices such as jigs and spirals can be used for coarser particle size classes while proven enhanced gravity concentrators can be used for scavenging fine particles.
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, spirals require a minimum of …
Knelson ™ Continuous Gravity Concentrator is an enhanced automated gravity separation system that has been developed specifically to address the requirement for high concentrate mass yield. It can be found operating at numerous sites worldwide providing excellent mineral separation and recovery.
To determine the full-scale recoveries of a potential mining operation, bench-scale gravity concentration testing is a crucial mineral beneficiation process. For the most accurate results, Met-Solve uses a variety of mineral processing equipment like spirals, shaking tables, and analytical tables, but our specialty lies in centrifugal gravity …
Spiral concentrators are used in mineral processing for separating minerals. Multotec Australia has a range of gravity concentration equipment for effective mineral concentration. The range comprises end-to-end spiral solutions, from process audits and test work, to complete spiral concentration plants optimised for your specific process.
Falcon Continuous (C) Gravity Concentrator. Falcon C Gravity Concentrators are primarily used to maximize mineral recovery and reduce tonnage to downstream processes. The Falcon C is capable of collecting fine minerals that would be missed by dense medium separators, spirals and other low G processes.
3 • Spiral Concentrators Spiral Operation Slurry enters the spiral through a feed box and is introduced on to the spiral surface. Once on the spiral surface, the mineral grains …

The Gravity Spiral Concentrator is a mineral processing device used for separating minerals based on their specific gravity. It works by utilizing the principles of gravity and centrifugal force ...
For the spirals to work efficiently the feed supply must have consistent characteristics and be of a constant rate. Variations in the flow rate, the feed size distribution, and percentage solids will have adverse effects upon separation. Generally, the solids tonnage should give adequate loading of the concentrate and …
Abstract. The different stages of the mechanism of concentration in spiral concentrators are discussed. The significance of many design and operational variables …
High gravity spiral concentrator is one such case that treats high dense particles (20 - 90% heavy mineral) within narrow sizes. Limited experimental work is focused on its separation phenomena in the past on such applications. As minerals flow down the spiral, particles of different sizes stratify due to combined factors such as centrifugal ...
Falcon C Gravity Concentrators. Falcon C Gravity Concentrators are primarily used to maximize mineral recovery and reduce tonnage to downstream processes. The Falcon C is capable of collecting fine minerals that would be missed by dense medium separators, spirals and other low G processes.
Spiral coal concentrators use the specific gravity of materials with different densities to separate coal, and produce a low-ash coal product at high efficiency. Our high-performance Coal Spirals deliver a feed capacity of 2 STPH to 3 STPH (1.8 mtph to 2.7 mtph) per start, dependent on raw coal quality and refuse amount to be discarded.
Breaking down how spirals work, he says material, generally sized at -1 mm, is mixed in a solids to water ratio of about 35%. The slurry is fed via distribution systems at a controlled rate into the top of a bank of spirals that usually contains between two and 12 spiral separators. The slurry flows under gravity down the spiral.
Knelson™ and Falcon Concentrators Popularized Gravity Centrifuges. The development of fluidized gold centrifuges has a rich history, starting in Australia in the 1930's. However, the equipment was not popularized …
Spiral concentrator is a modern high-capacity and a low-cost device. It is developed for concentration of LGOs and industrial minerals in slurry form. It works on a combination …
