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.

A gold concentrator is going to make your gold prospecting experiencing more efficient and enjoyable by speeding up the process of recovering finer particles of gold. When you know youve hit paydirt, you want to be sure that you are extracting every existing piece of gold. Thats why there are instruments such as micro sluice gold concentrators that can change the way you approach prospecting for gold.

Gold concentrators are aimed for the treasure hunter and gold prospector. At first, they may look somewhat imposing with their appearance, but these tools will change the way you approach prospecting for gold.

This tool is an item that uses centrifugal force in order to help with the recovery of gold. The goal is to make it possible to trap the highest percentage of gold possible. Now, thanks to more portable versions, anybody who is serious about hunting for gold can make full use of this approach to gold mining.

Gold concentrators are designed to focus on finding fine gold particles that would otherwise be missed. However, the particles of gold can be so fine that it resembles dust, making it difficult for it to be extracted via ways other than with gold concentrators. While it may not sound like much, this can quite easily accumulate in a short period of time making the extraction worthwhile.

There are also several other positives associated with gold concentrators. One huge positive is that no chemicals are used in the process of separating the gold. Instead, they merely use power and a little water with nothing else involved.

The other main positive is its efficiency. The amount of gold recovered compared to the power and costs involved in its operation is a huge benefit. In addition, the price to get started with gold concentrators is reasonable.

How gold concentrators work is relatively simple to follow. The process involved using gravity to then separate out the gold. As a direct result, you will be able to extract more gold than you would without a gold concentrator.

The gold concentrator primarily uses a cone tube in the heart of the machine. The material is fed into the base before being forced to use power from a motor. The G-force that is created as a result then allows the gold to be separated from the other material, thanks to the natural weight difference. The gold can then be collected with ease after the gold concentrator has finished processing.

There are several gold concentrators available and without any previous knowledge, deciding on the best one for your needs can be overwhelming. When you first begin weighing your options, you will notice there are two types: a zinc anodised and stainless steel version. We recommend purchasing the stainless steel option if you plan on prospecting for gold in or around saltwater. Over time, the salt would start to work against the zinc leading to parts having to be replaced. The zinc model is still a viable option, however, when using it around saltwater you will have to be extra cautious or limit your usage.

Aside from knowing which metal works best, you should also consider how much dirt you plan on putting through the machine over the course of an hour. This is linked to the size of the hopper as well as the power aspect, which is why you need to be aware of the engine and whether or not this can be expanded upon. You should also consider paying close attention to the number of revolutions associated with the gold concentrator.

Tables and bowls have been proven to be very effective for final cleaning. They are slow but very clean. They use no chemicals are safe for the environment and your family. They are fun and provide immediate gratification after each cleanup you will see high grade gold.

Regional mineral processing is becoming more common around the world. Miners are using iCON Gold Recovery equipment at their site and transporting a small volume of concentrate to regional processing plants. This is becoming the method of choice where hard rock miners have learned the value of their tails and are using the iCON to pre-concentrate the sulfides or entrapped gold.

This is the recommended method of the Global Mercury Program. Without pre-concentration the volume of material to treat and the amount of chemicals are tremendous. Concentration allows the operator to treat a reasonable amount of material either on site or at regional facilities serving many mines.

This is not recommended due to the environmental impacts and the effectiveness of the bowl and/or tables. When practicing whole ore amalgamation a miner will place mercury directly into the ball mill. In this case 100% of the ore is exposed to mercury. When a concentrator is used the amount of ore can be reduced dramatically to a small amount of concentrate. 1 ton (1000 kg) of ore could be reduced to 1 kg of concentrate. If the miner chooses to amalgamate the concentrate only a fraction of the mercury would be used and only a small percentage of the ore would be exposed to Hg.

The "i" series of concentrators use a batch process. Your cycle time will depend on the grade and weight of your feed. A heavy or rich feed will need a shorter cycle time. The iCON "i" concentrators can be cleaned out in around 3 minutes.

Hard Rock mining operations may have 100 grams of gold per ton of feed. This is very rich. In this case it is common to run for only 10 minutes between rinse cycles. You may choose to feed at ton per hour.When upgrading concentrates you will be processing rich and heavy material. In this case the cycle time may also be only 10 minutes. Here you may be feeding at ton per hour.

The throughput of the i150 Centrifugal Concentrator is nominally 2 tons per hour. If you have large material in your feed, if you have a heavy feed or if you are using iCON gravity concentrators to upgrade a concentrate the throughput will be reduced. All ores and all processes are different. Each user must assess their situation as with any mineral recovery process.

It is common for internet advertisements to show a process where a small amount of gravel goes in and a large quantity of bright shiny gold comes out. Experienced miners know this is not the case. A sluice box is a gravity concentrator. Lets say you put 1000kg of feed over your sluice. At the end of the day, you may have 20kg of concentrate. This concentrate is not bright and shiny, in fact, it looks just like the feed material. This material has to be post processed to further clean your cons and give you a sellable product. Although a sluice can give you a very high concentration ratio, it is not effective for recovering fine gold. In the case of sluice operations, miners are choosing iCON Gravity Concentrators to further concentrate the vast amount of material accumulate in the sluice.

When using an enhanced centrifugal concentrator, you may put up to 1000 kg into the process and get 1kg out. This will be a concentrate'. It will look just like the feed material. Some people choose to sell this concentrate while others choose to continue refining it to shiny, clean, high grade gold.
