Equipment to Recover Gold without Chemicals

A standard ball mill may grind your ore to 75 microns. Gravity Recoverable Gold (GRG) refers to how much gold you can recover based on how fine you are grinding/milling your ore. The GRG (Gravity Recovery Gold) testing is available. The number 1 application for iCON i350 worldwide is Hard Rock. The 1015 TPH capacity and the ability to recover

Fine Gold Recovery iCon Gravity Concentrator

iCONuses enhanced gravity to capture fine heavy minerals including Gold, Silver and Platinum. iCONuses a centrifugal field of up to 150 Gs to concentrate fine heavy minerals that are not recoverable by common artisanal and small scale mining methods. 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

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. Clean Water Connection The user will have to supply clean pressurized water to the concentrator. Connect your clean pressurized water supply to the hose barb on the plumbing manifold on the concentrator. 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. The water does not have to be perfectly

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. Hard Rock 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 20 minutes between rinse cycles. Alluvial operations with heavy black sand may run 20 minute cycles. Without black sand an alluvial cycle time may be up to 2 hours. 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 ½ ton per hour to the smaller i150. Every feed is different. The proper cycle time for you will be determined by analyzing/planning the free gold in your tails and adjusting your process to fit your ore.

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 closedcircuit or simply a screen in semiclosed circuit milling. After the mill the material will pass through the concentrator. The major mines have a recyclic load. Their processes are d

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. 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

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 ½ 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. To give complete confiden

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.

Freemilling gold ores are defined as an ore from which standard cyanidation (which takes about 2030 hours) can extract more than 90 % of the gold, under the condition that the ore size is 80 % <75 µm (Joe Zhou, 2004). Complex ores, meanwhile, require significantly higher cyanide or oxygen levels to attain an economic recovery (Brooy, 1994).
