What is a Falcon Concentrator?

What is a Falcon Concentrator?

An enhanced gravity separator (EGS) commercially known as the Falcon Concentrator has been evaluated for its ability to treat fine coal. Due to an insufficient centrifugal force, the metallurgical performances achieved on the basis of ash rejection for the −37 μm size fraction of all coal samples were insignificant.

What is a gold concentrator?

A Knelson concentrator is a type of gravity concentration apparatus, predominantly used in the gold mining industry. It is used for the recovery of fine particles of free gold, meaning gold that does not require gold cyanidation for recovery.

How does a Falcon concentrator work?

Falcon concentrators are enhanced gravity separators (EGS) consisting of a fast spinning bowl. The bowl is fed from its bottom and uses centrifugal force to drain the slurry in a thin flowing film at its wall. In this case, the film flows over a retention zone that has no fluidization counter-pressure.

How does a Knelson concentrator work?

The Knelson Concentrator relies on an enhanced gravitational force together with fluidization process to recover even very micron sized particles. First water is injected into the rotating concentrating cone through series of fluidization holes. Then feed slurry is introduced through a stationary feed tube.

How does a shaking table work?

Shaking tables are rectangular-shaped tables with ribbed decks with a water film flowing on them. Water flowing along the long axis of the table slurries the fed sample. Low-density particles are transported in the fast-moving film, causing fine, high-density particles to fall into the beds behind rifles.

What is gravity concentration?

Gravity concentration can be defined as the process by which particles of different sizes, shapes, and densities are separated from each other by the force of gravity or the centrifugal force. Gravity concentration is at present the main concentration process in the mineral industry in terms of tons processed.

How do spirals work?

It works on a combination of solid particle density and its hydrodynamic dragging properties. The spirals consist of a single or double helical conduit or sluice wrapped around a central collection column. The device has a wash water channel and a series of concentrate removal ports placed at regular intervals.

What are the fundamental operations in mineral processing?

Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation.

What does an oxygenator do?

n simple terms, an oxygen concentrator is a medical device designed to boost the blood-oxygen concentration of patients who suffer from low levels of oxygen concentration in their blood. The device can be powered by a battery or plugging it into an electrical outlet.

How does a gold shaking table work?

On a gold sluice, large particles (gravel) travel by sliding and rolling over the riffles, with finer particles travelling by saltation. On a gold shaker table, those particles are allowed to settle as they will get transported to the other end by the vibrating/shaking back-and-forth motion.

Why flat surface in shaking tables are inclined slightly?

A very important operating variable of a shaking table is the tilt adjustment. Normally, the feed side is lower, and the concentrate end is higher on the table, which creates an upward slope where the heavy material will ascend, while the light density material will not, and consequently, flow over the riffles.

How does the Falcon UF gravity concentrator recover gold?

This gold would normally be lost to tailings, but the UF has the power necessary to recover the gold from this carbon-gold slurry. No other gravity concentrator is efficient enough to separate these ultrafine particles. Using up to 600Gs of force, the Falcon UF Gravity Concentrator can recover and upgrade particles as fine as 3 micron.

What is a centrifugal Falcon Concentrator?

Laboratory Centrifugal FALCON Concentrator. The Falcon L40 enhanced gravity concentrator has a bowl diameter of 4” and is specifically designed for laboratory test-work on small ore samples. Applications include the concentration and upgrading of gold, platinum group metals, mineral sands, chromite, tin, tantalum, tungsten, iron ore,…

What is a Falcon SB gravity concentrator?

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.

Can sepsepro’s Falcon Concentrators perform gold recovery?

Sepro’s Falcon Gravity Concentrators are high G-force units that improve the efficiency of fine mineral recovery. Each of our three models has a specific purpose and situations where it can help optimize your mineral processing project. With this in mind, our team is often asked which concentrators can perform fine gold recovery.
