iCON is a family of Mineral Processing Products specifically designed to recover fine gold. iCON was designed by the professional Engineers at Falcon Concentrators and uses the same patented technologies used at the largest mines in the world.
iCON uses the same proven technology as the Falcon brand of professional mining products: it was designed by Falcons engineers and is now a product of iCON Gold Recovery Corp. Our History and Environmental Responsibility are discussed on our website.
Throughout history gold processing has been plagued with inefficiency and contamination. Millions of dollars of fine gold have been discarded in the tails or washed down the creek due to inadequate processing.
Processing large material that is known to have no value costs both money and time. With classification, time, energy and money will not be wasted processing excess material that is known to have no value.
For example, if you know that your largest gold is .5mm then there is no reason to put 10mm material through your process. Also, the large feed will affect the efficiency on any process. The large material will hinder the recovery of the finer materials.
Your feed will be screened to 2mm (or less based on your results) before processing in the concentrator. Any material larger than the screen will pass over the nugget trap. This will give the user confidence that they are collecting the BIG gold while minimizing the feed to the concentrator and maximizing its efficiency.

Knelson centrifugal concentrator is a centrifugal mineral processing equipment, it has features of high recovery rate, easy operation, etc. It is mainly used for recycle heavy materials in mineral particles, especially good for placer gold mining. Deya Machinery produces automatic discharging and semi-automatic discharging concentrator.
Centrifugal concentration has been proved an effective technique for recovering fine or ultra-fine heavy minerals for many years. In centrifugal concentration, the centrifugal force acting on a particle can be much greater than the acceleration of gravity; as a result, the settling velocity of particles increases greatly. The higher the centrifugal intensity (the centrifugal acceleration over gravity acceleration, often noted g), the finer the particles that can be recovered.
Since the first unit was commissioned in 1980, thousands of Knelson concentrators were installed. In recent years, the Knelson Concentrator has become the preferred gravity device to recover free gold. Compared to other centrifuges, it possesses quite different features either in design or separation mechanisms.
One unique feature of the Knelson Concentrator is its riffle construction andtangential fluidization water flow in the separating bowl,which partially fluidizes theconcentrate bed. As a result,the unit can achieve high recovery over a wide size range.Industrial recoveries of gravity recoverable gold have been measured as high as ninetypercent. Recovery is strongly influenced by feed rate and gangue density.
Knelson Concentrators have a large throughput capacity,e.g. a 76 cm KnelsonConcentrator can treat up to 40 tonnes of material per hour. Locating the Knelson within the grinding circuit can eliminate the need for other gravityrecovery devices. Another advantage of the Knelson is its ability totreat a wide size range of material without desliming,something most other centrifugescannot do.
The Manual Discharge Knelson is especially suitable for the recoveryof very low grade high density particles, typically on account of the limited concentratevolume. It develops a centrifugalintensity of 60 g,and can process feeds finer than6 mm. The feed is introduced to the bottom of the bowl by gravity through a downcomer. The feed requires only enough water for transport, and any density from 0 to 70% solids can be handled without any detrimental effect on operating efficiency.
Under the effect of the centrifuga1 force field. the heavy particles will report to the riffles as concentrate. whereas gangue minerals will flow to the outer rim as tails. The centrifugal force that would cause packing of material in the rings is partially offset by the fluidization water. The water jets are tangentially injected into the bowl from small holes on the Knelson Concentrator bowl in a direction opposite to the bowls rotation.
The resulting fluidized bed behaves as a heavy liquid whose density is that of thepulp, and hindered settling conditions prevail. It is in this constantly agitated environmentthat concentration takes place with the particles of higher specific density displacing thelighter ones.
Very high concentration ratios can be achieved, even above 500, at little or no loss of recovery. The Manual Discharge Knelson is a batch machine. The feed must be interrupted while concentrate removal takes place. This takes from 5 to 10 minutes, and is accomplished by unlocking an access door, removing a drain plug and flushing the concentrate to a secure gold room via a pipeline or into a container.
The manual discharge of its concentrate makes frequent flushing difficult,yieldingloading cycles of two hoursor more. Although virtually no gold operation can boast gold feed grades that would overload the Knelson over such recovery cycles, loss ofrecovery due to concentrate bed erosionshould requireshorter recovery cycles.
The Knelson Concentrator requires little maintenance. It is sturdy and has onlyone moving part,the rotor. Its drive shaft passes through two pillow-block bearings, wetted surfaces are made of stainless steel, and the concentrating bowl is moulded inwear-resistant polyurethaneor stainless steel.
The removal of concentrate can be accomplished automatically in less than twominutes. The feed is first diverted (generally to a cyclone pump sump or bal1 mill), the fluidization water flowrate and the speed of rotation are reduced. The concentrate is then flushed from the concentrating rings past the feed deflector and piped directly to a secure gold room.
The machines utilise the principles of a centrifuge to enhance the gravitational force experienced by feed particles to effect separation based on particle density. The key components of the unit are a cone shaped concentrate bowl, rotated at high speed by an electric motor and a pressurized water jacket encompassing the bowl. Feed material, typically from a ball mill discharge or cyclone underflow bleed, is fed as a slurry toward the centre of the bowl from above. The feed slurry contacts the base plate of the vessel and, due to its rotation, is thrust outward. The outer extremities of the concentrate bowl house a series of ribs and between each pair of ribs is a groove. During operation the lighter material flows upward over the grooves and heavy mineral particles (usually of economic value) become trapped within them. Pressurized water is injected through a series of tangential water inlets along the perimeter of each groove to maintain a fluidized bed of particles in which heavy mineral particles can be efficiently concentrated. The Knelson concentrator typically operates as a batch process, with lighter gangue material being continuously discharged via overflow and a heavy mineral concentrate periodically removed by flushing the bowl with water.

Main parts of centrifugal concentratorfeeding, rotor, groove, motor, backwash water, PU lining plate, bearing, frame, tailings and concentrate discharge, etc. Working principle of centrifugal concentrator The rotor of the centrifuge rotates at a high speed. Under the action of centrifugal force, heavy minerals are stacking on the inner plate groove of the rotor cone, and the light ore particles are gradually discharged. After about 4-6 hours of operation, stop feeding, and turn on the backwater to wash out the gold concentrate. Gold centrifugal concentrator is useful in the gold recovery in all ranges of particle size. It is most especially useful for recovering fine gold which gets lost during the operation of gravity concentrators. The application has shown that the recovery of gold can be very high, as much as 99% and the concentration ratio is up to 1,000 times. In the recovery of natural gold in lode ore that has a particle size of -0.074mm, the gold recovered is about 98%, for recovery of gold in particle size of 0.004mm, it is up to 97%.
