The i150 Gravity Concentrator is the smallest of the World famous iCONs. This is a gravimetric concentrator that uses enhanced gravity (Gs) to concentrate the free heavy minerals.It is also known as a centrifugal concentrator because of the centrifugal action of the spinning bowl. The process uses only water and an electric motor to concentrate the precious heavy minerals from a slurry.

iCON is a family of mineral processing equipment specifically designed to recover fine gold and other precious metals including such as silver, paladium and platinum. The product line includes concentrators, slurry pumps, vibrating screens and modular plants.

iCON was designed by the professional mineral processing engineers of Falcon concentrators. iCON has all the quality, reliability and performance you would expect from Canadian designed and patented equipment.

iCON integrates the proper level of sophistication for small scale and artisanal miners. There are no complicated computer controls. iCON can be serviced with hand tools available in remote and/or developing areas of the world.

Its fine gold recovery features were designed for the United Nations Global Mercury Project. iCON has the support of many governments around the world for its ability to recover precious metals without the use of Mercury or Cyanide.

Upon entering the spinning bowl, the feed begins to spin. As it climbs the bowl the material is stratified/classified by weight. The heavy particles are trapped in within the fluidized riffles. The bowl is periodically rinsed producing a rich concentrate.

Cycle Time: iCON concentrators require only 1 to 1.5 minutes to rinse the rich concentrate from the bowl. Simply pause the feed, slow the bowl to minimum RPM and gently rinse the riffles with the rinse wand. Then resume full rpm and continue feeding the slurry. A typical process may involve feeding for 1 hour then rinsing for 1.5 minutes: repeating.

All iCON products include a Variable Frequency Drive. This allows the user to specify the RPM of the motors. The VFD is an inverter which conditions the power allowing for smooth and predictable operation due to unstable electricity in your mining region or erratic generator output. The VFD is also a Soft Start which minimizes the in-rush current and allows the motors to start with minimum load on your generator.

In order to install your iCON you will have to consider the following: suitable footing, electrical supply, clean/pressurized water supply, feed method, tails removal method, concentration collection. You will also need to consider the height of the concentrator relative to the slurry input and tails output.

It is important to use the same size hose as the barb to supply this process water. A smaller hose, long hose or hose with bends/restriction will restrict the water flow and limit the pressure to the concentrator.

The process water should be fed from a dedicated supply line and pump. Connection to a manifold where other people may be using this same supply may cause wild fluctuation in the pressure and lead to unpredictable gold recovery.

When the supply pump is located near the concentrator, a HP centrifugal pump is generally sufficient. If the pump has to lift the water vertically or over a long distance the pump capacity may reach 2 HP or more.

One will have to consult the pumps curves to know if it will be sufficient for long runs or high lifts. Domestic/City water is typically not sufficient due to long supply runs and small diameter pipes. Garden hoses will always be problematic due to their long length and tendency to kink/bend.

The i-CON is the newest addition line of world class enhanced gravity concentrators for the recovery of precious metals and heavy minerals.The i-CON is personal, small scale mining equipment which provides artisanal, small scale and recreational miners state of the art technology in centrifugal concentration.

Although produced for small scale mining, the i-CON is backed by 20 years of experience producing enhanced gravity concentrators for the worlds largest industrial mines. It is a fully functional primary concentrator that has been designed to be a compact, easy to use, fully portable mineral processing solution. It is designed to be very reliable and contains only one moving part.

The i-CON will allow small scale and artisanal miners to recover dramatically finer particles of gold and related minerals than is possible with any other small scale or traditional mining system. In many mining areas the fine particles are the most common; however, these are often unintentionally discarded due to inappropriate concentration practices and are never recovered.

The i-CON, with its variable speed 150 G force concentration system, will allow the capture of these valuable fine particles. It will not only increase the value of every kilogram of material mined by recovering precious metal that was previously discarded due to inefficient concentration practices, but it will also greatly reduce (and hopefully eliminate) the dependency of these miners on mercury and other harmful, toxic chemicals.

Through the involvement and cooperation of leading international aid and development organizations, the i-CON Project has the capability of being the center of large, cooperative, community improvement projects.

The i-CON has the potential to make a significant difference to the lives of people engaged in small scale and artisanal mining around the world by not only increasing income, but also by reducing the use of toxic chemicals at the same time.

The iCON 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 series concentrators can be cleaned out in 1 minute.

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 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.

The number 1 application for iCON i150 worldwide is Hard Rock. The 2TPH capacity and the ability to recover fine, flat milled gold are ideal for iCON. The major mines of the world use gravity concentration in their grinding circuits. The concentrators can recover over 90% of the overall production of major/professional mines.

A typical Hard Rock application would involve a crusher and ball mill. The material would be size classified using a cyclone in closed-circuit or simply a screen in semi-closed circuit milling. After the mill the material will pass through the concentrator. The major mines have a recyclic load. Their processes are designed for the feed to pass through a concentrator multiple times before passing to the tails.

A Hard Rock operator may choose to run 1.5 tons per hour of a high grade ore. He may choose to rinse the bowl every 20 minutes. Here, he would have run 500 kg in 20 minutes and collected 1 kg of concentrate. That is a concentration ratio of 500 to 1.

The concentrate will still need to be upgraded or cleaned to have a sellable product. Some miners around the world are choosing to collect the concentrates from multiple mine sites and clean the cons at a regional secure facility. This is known as pre-concentration.

When scavenging old tails the operator must understand that there is a reason the first miner missed this gold. It may be that it was poorly milled and needs to be re-milled to liberate more gold. In order to recover what another team missed the operator must pay attention to the details and be prepared to adjust their process as required. To understand your ore and how much gold you can expect to recover, IGR recommends testing your samples at lab.

This photo shows what your concentrate may look like.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 50kg 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 to reprocess old tails and recover the values left behind by sluice operations.

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.

Any placer miner or dredger understands the vast amount of concentrate you will accumulate. They also understand the incredible amount of work required to clean the cons. Considering that a concentrate is already heavy, an i150 operator may run 1 tph through a concentrator. He may choose to rinse the bowl every 6 minutes which means after each 100 kg of feed. Here the i150 will produce 1 kg of cons from 100 kg of feed.

Placer miners also understand the need to classify their concentrate. Lets say a placer miner is processing inch material. He will have this coarse material and the finest sands in his sluice concentrate. The first step here is to classify or separate this concentrate into at least 2 sizes of material. The iCON IGR 100 Plant will handle this process for you. The screen will separate you material into 2mm+ and 2mm- sizes. (+/- 10 mesh) The fine material will be pumped to the concentrator and the coarse material will go to the nugget trap.

You may choose to wash your sluice directly into an iCON Slurry Pump. The pump could then move the material to your screen to greatly reduce the daily labor involved in cleaning your sluice, lifting, storing and transporting the material.

The small physical dimensions of the i150 and IGR 100 Plant make them mobile. The internal structures make them easy to clean from batch to batch or sample to sample. The i150 capacity makes it ideal for processing samples from individual drill holes. Overall the i150 is ideal for processing any volume from individual drill holes up to bulk sampling at 2 tons per hour.

The iCON IGR 1000 Plant can process up to 10 tons per hour. It is skid mounted for mobility. For larger volume bulk sampling the IGR 1000 Plant may be right for you. This pilot plant will give you confidence in the various values across your deposit and in the process of using a grizzly, scrubber, screen and concentrater.

Tables and bowls have been proven to be very effective for final cleaning. 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 processing is becoming more common around the world. Miners are using iCON 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 their product.

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 bowls and/or tables. When practising whole ore amalgamation a miner will place mercury directly into the ball mill or sluice. 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.

i150 has a Invertek VFD which is a single phase drive with 200-240/1/50-60Hz Single phase input and 230/3/60Hz 3 phase output. The motor is a 3 phase motor 208-230/3/60Hz which has to wire to the output of the VFD.

John Richmond, the founder of Sluice Goose Industries and the inventor of Goldrop, wanted to change the lives of millions around the world and make it easier for prospectors to make a living. The Goldrop will do both.

The Goldrop is designed to be portable, durable and easy to use. After a quick classification process the concentrate is simply dumped into the top of the Goldrop. Within seconds, over 99.8% of the gold is filtered and deposited into a canister at the base of the Goldrop. Thats it.

Shane from Klesh Guitars had the chance to review this product and had a lot to say:"If you're in a hurry to do paydirt and you want to get quick recovery, i think this machine is actually not bad at all. Especially for the bigger gold. It did 100% recovery on the beginner bag of paydirt, which is the big pieces of gold. On the Gold Strike, it was still up 95-85% recovery, which is still pretty good, especially for under a minute.That was really fast. And for the impossible paydirt, it still took me an hour to pan out the tailings. And it was still a around a 70% recovery rate within a minute. And that's really good."

The Goldrop then uses only water flow to separate the gold from the dirt in just seconds. Dirt can continuously be fed into the top of the unit. As the Goldrop separates the gold the tailings are fed out of the back of the unit into an optional bucket or back onto the ground.

At the bottom of the Goldrop is a collection jar. The jar will continue to collect gold as you feed in the pay dirt at the top. Theres no need to remove the jar until its full. If you want to inspect the jar you remove it while the Goldrop continues to separate the gold. Once the jar is reattached and the valve is opened, all the gold will instantly fall that was processed while the jar was removed.

Q: Hi I've collected black and ruby sand off of the beach here locally and done both panning and used a rotating wheel with water to try to separate the gold with no luck. The gold is actually smaller and lighter than the sand. I will see 2 r 3 specs in the pan and they will disappear before I get to the bottom of the pan and the rotating wheel was a bust because even at the point that sand was making it into the collection cup with an occasional flake most was being washed to the bottom and eventually lost. Will this collection system you're advertising collect that super fine flour gold ?

Gravity concentration was the dominant mineral processing method for about two thousand years. and it is only in the twentieth century that its importance has declined, with the development of such processes as flotation, magnetic separation and leaching. Gravity concentration is still the main method to treat most iron, tungsten, and tin ores, beach sands, and some rare metal ores such as tantalum and niobium. Gravity also plays an important role in the production of gold because of its high specific density(19.3) and natural occurrence as liberated species.

The gold concentrates produced by gravity equipment such as Knelson Concentrators, jigs and spirals are called gravity concentrates, and are normally pumped to a secured area, the gold room, for further upgrading. The tails and middlings of the gold room cleaner are also concentrates of a sort, as they generally contain liberated gold at a significantly greater concentration than in the ore itself.

Upgrading of the gold is achieved by rejecting gangue minerals and tramp metals (steel and copper) whilst retaining free gold particles. For gold-bearing sulphide ores, the main gangue minerals in gold gravity concentrates are pyrite and arsenopyrite, with small amounts of magnetite. For oxide ores, the gold concentrates may contain some heavy minerals, such as cassiterite, magnetite, ilmenite, rutile, zircon and monazite.

Tramp steel can be rejected by magnetic separation, and tramp copper, usually blasting wire, can be washed out of the final concentrates using nitric acid. Gangue minerals, however, are typically rejected using gravity methods. This proves particularly challenging for higher density minerals, such as sulphides and some oxides.
