Gold Recovery, iCON Gold Recovery, Gravity Concentrators ...

Hard Rock miners around the world have historically recovered as little as 30% of their free gold using mercury amalgamation. The iCON process is being used to scavenge/reprocess old tails without using mercury. These miners are now recovering more gold reprocessing tails with iCON than the original miners recovered. Hard rock miners must first understand some definitions: 1. Free Gold is liberated and depending on its size will be visible in a pan. 2. Free Milling Gold is the gold that can be liberated by a standard rotating ball mill. 3. Refractory Gold is that which is not recoverable by standard milling and/or chemical processes. This may be entrapped in sulfides39;. A standard ball mill may grind your ore to 75 microns. Fine grinding is one process available to liberate refractory gold. 4. Gravity Recoverable Gold refers to how much gold you can recover based on how fine you are grinding/milling your ore. The GRG testing is available at Met Solve La...

Alluvial miners often ignore the fine gold because sluices and jigs cant catch it. Depending on the size and shape of your gold a sluice may begin to lose gold at 40 mesh. Some alluvial mining deposits have 90% of their gold finer than this where enhanced gravity, iCON, is the only solution. Concentrators are being tested on the ends of sluices and dredges. In this case the operation is still capturing the same amount of gold in the sluice. The added value of the concentrator becomes very clear. After seeing the additional recovery of the concentrator some operators are choosing to redesign their process. An efficient plant design would include a screen where only the coarse material will be routed to a sluice and only the fine material will be routed to your concentrator. An example of this process is the iCON IGR 1000 Plant.

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, the 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 Gold Recovery Plant will handle this process for you. The screen will separate you material into 2mm+ and 2mm sizes. The fine material will be pumped to the concentrator and the coarse material will go to the nugget trap. To give complet...

The small physical dimensions of the iCON Gravity Concentrator and iPlant make them mobile. The internal structures make them easy to clean from batch to batch or sample to sample. The iCON capacity makes it ideal for processing samples from individual drill holes. Overall iCON mining equipment is ideal for processing any volume from individual drill holes up to bulk sampling at 2 tons per hour. The iCON IGR 1000 Gold Recovery Plant can process up to 10 tons per hour. It is skid mounted for mobility. For larger volume bulk sampling the IGR 1000 Gold Recovery Plant may be right for you.
